CHROME STEEL ALLOY

摘要

A chrome-steel alloy comprising 0.4 0.75 % carbon, 0.4 1.6 % manganese, 12 -19 % chrome, up to 0.2 % nickel, up to 0.7 % silicon, 0.5 1.5 % molybdenum, up to 1.5 % tungsten, 0.05 0.3 % vanadium and (%Ti / %Nb), 0.02 0.15 % sulphur, up to 0.1 % nitrogen and up to 0.008 % boron, residual iron including impurities caused by metal making. The steel alloy is characterized by good processibility, resistance to corrosion, resistance to wear, high resistance to heat (up to 300 DEG C) and high rigidity.
