C60 Steel Suppliers in China | AISI 1060 Factory for Medium Carbon Engineering Steel Products
C60 steel is an unalloyed medium carbon engineering steel which has 0.57%-0.65% Carbon as per EN10083 standard. It has characteristics similar to that of C55 carbon steel which has high hardness and high strength after hardening. C60 is difficult to weld, and machinability is poor due to high carbon content. This steel is generally supplied in an untreated or normalized condition.

Description: C60 is one of the higher carbon contents (0.60%) steels. It is more difficult to fabricate than the lower carbon grades.
Applications: Applications include hand tools such as screwdrivers, pliers and similar items.

Heat to 680-710°C, cool slowly in furnace. This will produce a maximum Brinell hardness of 241.
Normalizing temperature: 820-86°C/air.
Harden from a temperature of 800-840°C followed by water or oil quenching.
Tempering temperature: 550-660°C/air.

Forging: Hot forming temperature: 1100-800°C.
Machinability: Machinability of C60 and all of the higher carbon steels is relatively poor. C60 rates at 55 to 60 % that of the AISI 1112 steel which is considered 100% machinable.
Corrosion Resistance: This steel is not corrosion resistant. It will rust unless protected.
Welding: C60 may be welded by all of the conventional methods. However both pre-heat and post-heat should be used when welding by an approved procedure. Pre-heat at 260 to 320°C and post-heat at 650 to 780°C.
Cold working: Cold working is difficult even in the annealed condition although it may be done by conventional methods but requires greater force than the lower carbon steels.
C60 is an unalloyed medium carbon engineering steel with a carbon content ranging between 0.57% and 0.65% according to the EN10083 standard.
Due to its high hardness and strength after hardening, C60 is commonly used for manufacturing hand tools such as screwdrivers, pliers, and other similar mechanical items.
No, C60 steel is difficult to weld due to its high carbon content. If welding is required, it must follow an approved procedure including pre-heating at 260 to 320°C and post-heating at 650 to 780°C.
The machinability of C60 is relatively poor. It is rated at approximately 55% to 60% of the machinability of AISI 1112 steel, which is standardly considered 100% machinable.
Key heat treatments include: Soft Annealing at 680-710°C (furnace cool), Normalizing at 820-86°C (air cool), Hardening at 800-840°C (water or oil quenching), and Tempering at 550-660°C (air cool).
No, C60 steel is not corrosion-resistant. It will rust if exposed to moist environments unless it is treated with a protective coating or rust preventive oil.
