1. Cold work tool steel with high thoughness and full hardenability, also large dimensions.

2. High impact strength and compressive strength.

3. For oil and air hardening.

4. Good polishability.

Heat Treatment


610 to 650°C

Slow controlled 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. 285 HB.


Stress relieving

Approx. 650°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.



840 to 870°C

Oil, salt bath (300 to 400°C), air. Holding time after temperature equalization: 15 to 30 minutes.

Obtainable hardness:

53 - 57 HRC in air.

54 - 58 HRC in oil or salt bath.



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