C60 Steel (1.0601, DIN C60, AISI 1060) - High Carbon Steel from China Suppliers and Factory
GENERAL CHARACTERISTICS
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 & Applications
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 Treatment Process
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.

Diagram Tempering Temperature – Mechanical Properties
Hot forming temperature: 1100-800°C.
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.
This steel is not corrosion resistant. it will rust unless protected.
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 is difficult even in the annealed condition although it may be done by conventional methods but requires greater force than the lower carbon steels.
