Martensitic steel in its un-tempered hard form is much brittle for use. One of the methods to alleviate this difficulty is tempering. Tempering of quenched parts is required for majority of its applications. To get toughness tempering includes heating of steel at less than the lower-critical temperature, which is often 400-1105F or 205-595C as per […]

Heat treating is a process of heating or cooling metals and is used to alter their properties in order to obtain the desired shape and structure such as brittleness, hardness, and softness. The steps for achieving these things are consistent with all heat treatment processes. Heat treatment techniques include annealing, tempering, hardening, quenching, stress releasing […]
