Very few metals react to heat treatment in the same manner, or to the same extent, that carbon steel does, and carbon-steel heat-treating behavior can vary radically depending on alloying elements. Steel can be softened to a very malleable state through annealing, or it can be hardened to a state as hard and brittle as glass by quenching. However, in its hardened state, steel is usually fa… WebTempering steel is the process of slowly, accurately reheating the quenched metal to achieve the desired balance of ductility and hardness. Any irregularities in the steel when incorporating this process results in warped, distorted and damaged materials.
