1.2581(H21, X30WCrV93, SKD5) Hot-Work Mould Steel properties:

Tungsten-chrome-vanadium steel for hardening in oil and possibly in air with very good hardenability, very high firmness during the heat and resistance to the tempering, high resistance to the hot tempering and good toughness. Further the steel has a lower resistance to tearing of thermal fatigue and higher sensitivity to quick changes of temperature. The steel is not appropriate for tools cooled by water. It is well-workable during the heat and well-workable in the soft-annealed state.


1. High hot strength 

2. High retention of hardness

3. High heat checking resistance
