Steel properties :

Chrome-molybdenum-vanadium steel with big hardenability for hardening in oil and in air, especially high resistance to the wear (higher than by 1.2080), good cutting power, very good firmness in the pressure, lower toughness (but higher than by 1.2080). This steel shows good dimensional stability at the heat treatment, suitable for hardening to the secondary hardness (the possibility of nitriding). Further the steel is very difficult to sharpen, it works at the heat with difficulties and has a rather difficult workability in the annealed state.

Applications :

Cutting, punching, stamping tools, shear blades, thread rolling dies, drawing and bending tools, flanging and straightening rolls, deep drawing tools, plastic mould for abrasive polymers, cold extrusion dies, dawing dies etc.
