What Is 1060 Carbon Steel?
1060 carbon steel is a high-carbon steel grade known for its hardness, strength, wear resistance, and relatively low cost. It belongs to the 10XX carbon steel series, where the last two digits generally indicate the approximate carbon content. In the case of 1060 steel, the “60” refers to a carbon content of about 0.60%.
Because of this carbon level, 1060 sits at the lower end of the high-carbon steel range. High-carbon steels are typically harder and stronger than low-carbon and medium-carbon steels, but they are also less ductile and more difficult to weld.
1060 carbon steel is often used for parts that need durability, hardness, and resistance to wear. Common examples include knives, swords, shafts, axles, wear rails, clutch discs, machinery components, and certain construction applications.
1060 Carbon Steel Overview
1060 steel is valued because it offers a practical balance of mechanical performance and affordability. It is stronger and harder than many lower-carbon steels, while still being less expensive than many alloy steels, tool steels, and stainless steels.
The material is not stainless steel, so it does not offer strong corrosion resistance. If exposed to moisture, humidity, or outdoor conditions, 1060 carbon steel can rust unless it is protected with oil, coating, paint, plating, or another surface treatment.
Key characteristics of 1060 carbon steel include:
- High-carbon steel grade
- Approximate carbon content of 0.55–0.66%
- High hardness
- Good strength
- Good wear resistance
- Ferromagnetic behaviour
- Moderate ductility compared with lower-carbon steels
- Poor weldability compared with mild steel
- Low cost compared with many alloy and stainless steels
- Suitable for blades, shafts, axles, machinery parts, and wear components
1060 carbon steel is a good option when hardness and strength are more important than corrosion resistance, high ductility, or easy welding.
What Is 1060 Carbon Steel Used For?
1060 carbon steel is used in applications where hardness, wear resistance, toughness, and cost efficiency matter. Its high carbon content allows it to perform well in parts that experience friction, cutting action, impact, or repeated mechanical loading.
Because it can hold an edge reasonably well, 1060 steel is also used in bladed tools and weapons. It is common in knives, axes, swords, and katanas, although it requires maintenance to prevent rust.
Common applications of 1060 carbon steel include:
| Application Area | Example Uses |
|---|---|
| Cutting tools and blades | Knives, axes, swords, katanas, agricultural blades |
| Machinery | Shafts, axles, wear parts, machine components |
| Automotive and mechanical systems | Clutch discs, springs, drive components |
| Construction | Wear rails, structural parts, equipment components |
| Water and utility systems | Water mains and related steel parts |
| General manufacturing | Formed parts, machined parts, high-wear components |
1060 carbon steel is often selected when a part needs to be harder and stronger than mild steel, but does not require the corrosion resistance of stainless steel or the specialised performance of alloy tool steel.
Is 1060 Carbon Steel Good for Knives?
Yes. 1060 carbon steel can be a good material for knives because it offers useful hardness, toughness, and edge retention. It is not the hardest blade steel available, but it provides a balanced performance for many general-purpose cutting tools.
However, 1060 steel is not corrosion resistant. Knives made from 1060 carbon steel should be cleaned, dried, and lightly oiled after use to reduce the risk of rust. This is especially important if the blade is exposed to water, acidic foods, outdoor conditions, or humid environments.
Main reasons 1060 steel is used for knives:
- Good hardness
- Reasonable edge retention
- Good toughness for a high-carbon steel
- Lower cost than many premium blade steels
- Suitable for sharpening and maintenance
For users who want a low-maintenance knife, stainless blade steels may be a better choice. For those who prefer carbon steel performance and are willing to maintain the blade, 1060 can be a practical option.
Is 1060 Carbon Steel Suitable for Katanas?
Yes. 1060 carbon steel is commonly used for katanas and other swords. It offers a useful combination of hardness, toughness, and affordability, which makes it suitable for functional and decorative sword applications.
Its carbon content allows the blade to be hardened enough for cutting performance, while still retaining enough toughness to reduce brittleness compared with some higher-carbon steels. This balance is one reason 1060 is frequently used in entry-level and mid-range swords.
That said, the final performance of a katana depends not only on the steel grade, but also on:
- Heat treatment
- Blade geometry
- Forging quality
- Tempering process
- Edge design
- Surface finish
- Maintenance
Like knives, 1060 carbon steel swords can rust if they are not properly cared for.
How Is 1060 Carbon Steel Made?
1060 carbon steel is made by melting and refining iron with controlled amounts of carbon and other elements. The starting material may include pig iron, scrap steel, or a combination of both.
When pig iron is used, the melt may contain more carbon than required. Oxygen can be introduced into the molten metal to oxidise and reduce excess carbon. Impurities rise to the surface as slag, which can then be removed.
After the base steel has been refined, carbon and other elements are adjusted to meet the required composition. The molten steel is then cast into forms such as:
- Ingots
- Billets
- Slabs
- Bars
- Plates
The steel can then be processed further by hot rolling, cold rolling, heat treatment, cutting, machining, grinding, or forming.
Chemical Composition of 1060 Carbon Steel
The defining feature of 1060 carbon steel is its carbon content. Compared with mild steel and medium-carbon steel, 1060 contains more carbon, which increases hardness and strength.
Typical chemical composition of 1060 carbon steel
| Element | Typical Content |
|---|---|
| Iron | 98.35–98.85% |
| Manganese | 0.60–0.90% |
| Carbon | 0.55–0.66% |
| Copper | Up to 0.50% |
| Silicon | 0.04–0.35% |
| Sulfur | Up to 0.05% |
| Phosphorus | Up to 0.04% |
Iron is the base element, while carbon is the main strengthening element. Manganese contributes to strength and hardenability, while silicon is usually present in smaller amounts.
Carbon Content of 1060 Carbon Steel
1060 carbon steel typically contains 0.55–0.66% carbon. This places it at the beginning of the high-carbon steel category.
Carbon content has a major effect on steel behaviour. As carbon increases, steel generally becomes harder and stronger, but also less ductile and less weldable. This explains why 1060 steel can perform well in blades and wear components, but is harder to weld than mild steel.
Effects of carbon in 1060 steel:
- Increases hardness
- Improves strength
- Improves wear resistance
- Helps edge retention in blades
- Reduces ductility
- Reduces weldability
- Increases risk of cracking during welding or improper heat treatment
For applications that require significant bending, forming, or welding, a lower-carbon steel may be easier to work with.
Mechanical Properties of 1060 Carbon Steel
1060 carbon steel provides good strength and hardness for a plain carbon steel. Its exact mechanical properties depend on the product form and heat treatment condition.
Typical mechanical properties
| Property | Typical Value |
|---|---|
| Density | 7.85 g/cm³ |
| Yield strength | 485 MPa |
| Hardness | 89 Rockwell B |
| Magnetism | Ferromagnetic |
| Machinability rating | Around 57% |
Because 1060 can be heat treated, actual hardness and strength can vary significantly. A hardened and tempered 1060 component may behave very differently from hot-rolled or annealed material.
For critical parts, always confirm the required condition, hardness, strength, and test certification with the material supplier.
Is 1060 Carbon Steel Magnetic?
Yes. 1060 carbon steel is magnetic. It is an iron-based steel and is considered ferromagnetic.
This magnetic behaviour can matter in applications involving magnetic fixtures, inspection equipment, sensors, electric motors, or sorting systems. It also distinguishes 1060 steel from non-ferrous metals such as aluminium, copper, and brass.
Machinability of 1060 Carbon Steel
1060 carbon steel has moderate to low machinability compared with many other steels. Its machinability rating is typically around 57%, meaning it can be machined but may require more care than softer low-carbon steels.
Machinability is affected by hardness, condition, cutting speed, tooling, coolant, and heat treatment. Hardened or tempered 1060 steel is more difficult to machine than softer forms.
Machining tips for 1060 carbon steel:
- Use sharp tools
- Use suitable coolant or cutting fluid
- Avoid excessive heat buildup
- Use rigid workholding
- Adjust feeds and speeds based on hardness
- Machine softer conditions before final hardening where possible
- Consider grinding for hardened parts requiring tight tolerances
Recommended cutting conditions vary depending on tooling and setup, but 1060 generally requires more conservative machining than mild steel.
Main Characteristics of 1060 Carbon Steel
1060 carbon steel is best known for its hardness, strength, wear resistance, and affordability. It is not the most ductile or corrosion-resistant steel, but it performs well when used correctly.
Important characteristics include:
High hardness
The carbon content allows 1060 steel to achieve good hardness, especially after heat treatment.
Good tensile strength
1060 is stronger than many lower-carbon steels.
Wear resistance
Its hardness makes it useful for parts exposed to sliding, cutting, or abrasive contact.
Ferromagnetic behaviour
Because it is iron-based, 1060 steel is magnetic.
Moderate ductility
It is less ductile than mild steel, but still workable in the right condition.
Low corrosion resistance
1060 steel can rust and usually needs protection in corrosive environments.
Is 1060 Carbon Steel Mild Steel?
No. 1060 carbon steel is not mild steel.
Mild steel is a low-carbon steel, usually containing approximately 0.05–0.30% carbon. 1060 carbon steel contains around 0.60% carbon, placing it in the high-carbon steel category.
This higher carbon content gives 1060 steel more hardness and strength than mild steel, but also makes it less ductile and more difficult to weld.
1060 carbon steel vs mild steel
| Feature | 1060 Carbon Steel | Mild Steel |
|---|---|---|
| Carbon content | About 0.55–0.66% | About 0.05–0.30% |
| Steel type | High-carbon steel | Low-carbon steel |
| Hardness | Higher | Lower |
| Strength | Higher | Lower |
| Ductility | Lower | Higher |
| Weldability | Poorer | Better |
| Corrosion resistance | Low | Low |
Mild steel is usually better for general fabrication, welding, and forming. 1060 is better when hardness, wear resistance, and strength are more important.
Is 1060 Carbon Steel Strong?
Yes. 1060 carbon steel is strong compared with many common metals and low-carbon steels. A typical yield strength value is around 485 MPa, although actual strength depends on processing and heat treatment.
Its strength makes it suitable for shafts, axles, wear parts, and blade applications. However, it is not automatically the best choice for every high-strength application. Some alloy steels and heat-treated tool steels can provide much higher strength, better toughness, or improved fatigue performance.
Is 1060 Carbon Steel Weldable?
1060 carbon steel has poor weldability compared with mild steel and many low-carbon steels. Its higher carbon content increases the risk of brittleness and cracking in and around the weld zone.
One common concern is hydrogen-induced cold cracking, especially if the material is welded without proper preparation. Preheating can help reduce risk, but welding 1060 still requires care.
Welding considerations for 1060 steel:
- Preheating may be required
- Hydrogen control is important
- Post-weld heat treatment may be needed
- Avoid rapid cooling after welding
- Use appropriate filler material
- Consider whether a lower-carbon steel would be better for welded structures
For important welded parts, a qualified welding procedure should be used.
Common Forms of 1060 Carbon Steel
1060 carbon steel is available in different forms depending on the manufacturing process and application. The same base composition can behave differently depending on whether it is hot rolled, cold rolled, annealed, hardened, or tempered.
1. Hot-Rolled 1060 Carbon Steel Plate
Hot-rolled 1060 plate is processed at elevated temperatures. This makes the material easier to shape and usually results in lower cost than cold-rolled material.
Hot-rolled 1060 carbon steel is generally less hard and less dimensionally precise than cold-rolled steel, but it is more ductile and easier to form. It is useful for structural, construction, and wear-related applications where tight surface finish is not the main requirement.
2. Cold-Rolled 1060 Carbon Steel Plate
Cold-rolled 1060 plate is processed at or near room temperature. This improves strength, hardness, dimensional accuracy, and surface finish.
However, cold rolling also increases internal stress and brittleness. Stress relieving may be needed before further processing. A common stress-relieving approach involves heating the steel to approximately 550–650°C and then allowing it to air cool slowly.
Cold-rolled 1060 is useful when better surface finish, tighter tolerances, or higher strength are needed.
3. 1060 Carbon Steel Bar
1060 bar stock is used for machined components, shafts, pins, axles, and mechanical parts. It can be supplied in round, square, flat, or rectangular forms.
Bar stock is commonly machined before final heat treatment when high hardness is needed.
4. 1060 Carbon Steel Sheet
1060 sheet is used where thinner high-carbon steel material is required. It may be cut, formed, stamped, or heat treated depending on the application.
Because of its carbon content, 1060 sheet is not as easy to form as lower-carbon sheet steel.
5. Hardened and Tempered 1060 Steel
1060 carbon steel can be hardened and tempered to improve strength, hardness, and performance. This condition is common for blades, wear parts, and other components that need a balance of hardness and toughness.
Heat treatment must be controlled carefully to avoid excessive brittleness, distortion, or cracking.
Equivalent Grades of 1060 Carbon Steel
Equivalent grades vary by country and standard. These grades may be similar, but they are not always identical in chemical limits, mechanical properties, or heat treatment response.
Common 1060 carbon steel equivalents
| Region / Standard | Equivalent Grade |
|---|---|
| EU | C60 |
| Germany | C60 |
| United Kingdom | 070M60 |
| Italy | 1C60 |
| Japan | S58C |
| China | 60 |
| Russia | 60 |
When sourcing 1060 steel internationally, confirm the exact specification, product form, heat treatment condition, and material certificate before substituting one grade for another.

A stainless steel or coated material is usually better where corrosion resistance matters.
Is 1060 Carbon Steel Expensive?
No. 1060 carbon steel is generally considered an affordable material. It may cost more than low-carbon or medium-carbon steel because it contains more carbon and can require additional processing, but it is still usually much cheaper than stainless steel, high-speed steel, and many specialised alloy steels.
Material price can vary depending on:
- Product form
- Thickness or diameter
- Heat treatment condition
- Quantity ordered
- Certification requirements
- Market conditions
- Supplier location
As a general material category, 1060 is often chosen when manufacturers need higher hardness and strength without moving to a premium steel grade.
1060 Carbon Steel vs Ordinary Steel
1060 carbon steel differs from many ordinary steels mainly because of its higher carbon content. This carbon content changes the material’s hardness, strength, ductility, machinability, and weldability.
Compared with low-carbon steel, 1060 is harder and stronger, but less ductile and harder to weld. Compared with stainless steel, 1060 is usually cheaper and can be harder, but it has much lower corrosion resistance.
| Feature | 1060 Carbon Steel | Low-Carbon Steel | Stainless Steel |
|---|---|---|---|
| Carbon content | High | Low | Varies |
| Hardness | High | Low to moderate | Varies |
| Strength | Good | Moderate | Varies |
| Corrosion resistance | Low | Low | High |
| Weldability | Poor to moderate | Good | Grade-dependent |
| Cost | Low to moderate | Low | Higher |
1060 is best viewed as a practical high-carbon steel for hardness, edge retention, and wear applications, rather than a corrosion-resistant or highly weldable steel.
1060 Carbon Steel vs Medium-Carbon Steel
1060 carbon steel is generally harder and stronger than medium-carbon steel because it contains more carbon. Medium-carbon steels typically contain around 0.30–0.60% carbon, while 1060 sits at about 0.60%.
Key differences
| Feature | 1060 Carbon Steel | Medium-Carbon Steel |
|---|---|---|
| Carbon content | About 0.55–0.66% | About 0.30–0.60% |
| Hardness | Higher | Lower to moderate |
| Strength | Higher | Moderate to high |
| Ductility | Lower | Higher |
| Weldability | Lower | Better |
| Common uses | Blades, wear parts, shafts, axles | Gears, shafts, forgings, general mechanical parts |
Choose 1060 when hardness and wear resistance are the priority. Choose medium-carbon steel when better ductility, easier machining, or improved weldability is needed.
1060 Carbon Steel vs 1045 Carbon Steel
1045 carbon steel is a medium-carbon steel, while 1060 carbon steel is a high-carbon steel. The difference in carbon content affects hardness, strength, ductility, and weldability.
Key differences
| Feature | 1060 Carbon Steel | 1045 Carbon Steel |
|---|---|---|
| Carbon content | About 0.55–0.66% | About 0.45% |
| Steel type | High-carbon steel | Medium-carbon steel |
| Hardness | Higher | Lower |
| Strength | Higher | Lower to moderate |
| Ductility | Lower | Higher |
| Weldability | Poorer | Better |
| Edge retention | Better | Moderate |
| Common uses | Blades, springs, wear parts, shafts | Shafts, gears, pins, bolts, machine parts |
1060 is often preferred where higher hardness or edge retention is needed. 1045 is often better for machined mechanical components that need a balance of strength, toughness, and workability.
