ASM Handbook, Volume 4B: Steel Heat Treating Technologies expands coverage on equipment, control, troubleshooting, and problems associated with steel heat treating. New articles extensively address distortion and the prevention of cracking—including the modeling and simulation of distortion. Furnace equipment and controls are described in detail, along with quenching systems and characterization of quenchants for reliable and effective hardening. General process and procedure factors also are introduced—including temperature uniformity of furnaces, calculation of heat treating costs, decarburization, and more.
