Cold Die Steel
Cold Die steel has good resistance to oxidation at elevated temperatures, high hardness and good wearing properties.
lt is suitable for intricate sections, dies for blanking, coining, toller threading and drop forging hard materials.
The structure is martensitic on cooling in air but the carbides can be precipitated and the steel softened by very slow cooling from 840°C.
The standard oil hardening die steels contain 1 C, 1 Mn, 0,3-1,6 W, 0,5 Cr, hardened from 800°C and immediately tempered at 170-250°C. For cold obtrusion punches high-speed steels are satisfactory, e.g. 6W6 Mo.
