Hardening and tempering process
WebDec 19, 2024 · Tempering is most often performed after hardening processes. In these processes, the material is heated above its upper critical temperature followed by a … WebThe tempering operation is very important and must be performed on every piece which is hardened. Tempering should be done just as soon as the quenched part is cool enough to be comfortably handled in the bare hands. Tempering temperatures may vary from 225 o F. to as high as 800 o F., but the usual temperature is 400-800 o F.
