W.Nr. 1.2767
The steel for cold working with high Ni content, high toughness and hardenability, even for bigger cross-sections. High notch toughness and compression strength. Oil, vacuum and air hardenable.
Especially suitable for polishing, etching, patterning and electroerosion machining. It features very good wear resistance and relatively good dimensional stability during heat treating.
The steel has lower machinability.
The steel is the most suitable for highly stressed linings of moulds for injection and pressing of plastic materials, massive cutting tools for larger thicknesses, shears for cold cutting of larger thicknesses, scrap shears, etc.
For the most stressed tools for cold stamping, extrusion, pressing tools for cutlery, bending tools, shear blades for cutting of billets.
