1. A kind of cold work tool steel with excellent wear resistance and edge holding ability
2. High surface hardness after heat treatment.
3. Medium toughness, but high compressive strength, and good through hardening properties and dimensional stability.

Heat Treatment
800 to 850°C
Slow con trolled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C, further cooling in air.
Hardness after annealing: max. 250 HB

Stress relieving
650 to 700°C
Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or incomplex shapes.
After through heating, hold in neutral atmosphere for 1 to 2 hours.

950 to 980°C
Oil, salt bath (220 to 250°C or 500 to 550°C), air plast, still air. Holding time after temperature equalization: 15 to 30 minutes. Obtainable hardness: 64 - 66 HRC.
Special treatment: Hardening 1020°C and tempering at 500°C.
Obtainable hardness approx. 61 HRC (e.g. if followed by nitriding).

Slow heating to tempering temperature immediately after hardening/time in furnace 1 hour for each 20 mm of workpiece thickness but at least 2 hours/cooling in air. For certain cases we recommend to reduce tempering temperature and increase holding time.
