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.

1.2581(H21, X30WCrV93, SKD5) Hot-Work Mould Steel Applications
Tools for hot mechanical working such as highly stressed small pressing dies and die inserts especially for die forging of accurate products from the difficult-workable steels and copper alloys, thorns and jaws for forging presses, forgings for swaging, tools for production of rivets, nuts and screws, small extrusion dies (matrices), thorns, pressing discs for extrusion of alloys of non-ferrous metals.
