Effects of Silicon in High-Cr White Cast Irons
silicon has on the microstructure and heat treatment response of high-Cr white cast irons. Alloys of both ASTM A532 Class II and Class III were studied. Austenitizing heat treatment at a series of temperatures between 1600 and 2000 F (872 and 1090 C) was employed to help determine the optimum hardening tem-perature in each class of alloys.
Iron Classification Codes and Characteristics
formed in the solid state during heat treatment. The iron is cast as a white iron of a suitable chemical composi-tion to respond to the malleabilizing heat treatment. Alloyed iron—This classification includes gray irons, ductile irons and white irons that have more than 3% alloying elements (nickel, chromium, molybde-num, silicon or copper).
