Abstract
A cast iron alloy composition comprising 2.5-3.5% carbon, 0.5-1.0% manganese, 0.25-1.5% silicon, 13-19% chromium, 0.8-3.0% nickel, balance essentially iron which is machinable in the annealed condition and abrasion resistant in the hardened condition. The alloy may be annealed by furnace cooling, at a rate between 100.degree. C. and 350.degree. C./hr., from the austenitizing temperature, and hardened by air cooling from the austenitizing temperature.
