Designation by Standards
Chemical Composition (in weight %)
Low alloyed cold working tool steel.
Cold rolls, back-up rolls, straightening rolls, non-ferrous 2 and 4 high roll mills.

Continuous Cooling Transformation (CCT) Diagram
Time-Temperature Transformation (TTT) Diagram
Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Harden from a temperature of 800-820oC, 830-850oC followed by water or oil quenching. Hardness after quenching is 64-67 HRC.
Tempering temperature: 200-600oC.
Tempering Temperature (oC) vs. Hardness (HRC)
Hot forming temperature: 1150-850oC.
