Abstract
White cast iron containing nickel and chromium and having a discontinuous carbide phase is heated at a temperature of at least 450 DEG C. to transform the as-cast austenite, and is then slowly cooled at not more than 50 DEG C./hour to 200 DEG C. or below, whereby the hardness is increased. The process is particularly applied to alloys containing in percentage by weight. .carbon.2.8 - 3.2 .silicon.1.5 - 2 .manganese.0.4 - 0.7 .nickel.5.5 - 6.5 .chromium.7.5 - 9 .iron and.balance .impurities.
