Steel properties :

Nickel-chrome-molybdenum-vanadium steel for hardening in the stream of air or in oil with high hardenability. The steel has high hardness after hardening, good resistance to the tempering, good toughness and good firmness during the heat. Is resists quick temperature changes and also thermal fatigue. The steel is well-workable during the heat and well-workable in the soft-annealed state.

______________________________________________________________________________________________________________

Applications :

 

Tools for mechanical working during the heat such as dies of all sizes, especially with the firmness over Nmm2 for drop hammers and forging presses, extruders with the firmness over 1600 Nmm2 for extrusion of non-ferrous metals. The steel is appropriate for knives during the cold cutting of materials of thick thicknesses, knives for scrap iron. For pressing of plastic substances, big forces and breeze-blocks can be produced from this steel and these can be hardened in air.
