Heat Treating Overview Heat treating, as the name implies, is a series of treatments in which heat is used to alter the properties of a metal or alloy. Because time at temperature is also important, heat treatment can be further defined as a series of time-temperature treat-ments. Heat treatments are used for a variety of purposes, theRockwell Hardness (HRC, HRB) to Brinell Hardness (HB or a387gr11cl1 tensile Heat treatmentThe following two conversion tables come from standard ASTM A 370.
