ABSTRACT:
An abrasion-resistant high-chromium type of alloyed white iron, which can be hardened and toughened by refrigeration at sub-zero temperatures, containing as its essential alloying constituents about 2.6% to about 3.6% carbon, about 12% to about 22% chromium, about 0.5% to about 1.1% manganese, about 1.0% to about 3.0% molybdenum, about 0.5% to about 1.5% copper, about equal amounts of nickel and silicon in the range from about 1.4% to about 2.5% of each, and the balance iron along with conventional residual elements and incidental impurities present in usual amounts.
