Method Of Tempering

          Tempering of steel may be carried out in liquid bath such as oil, salt or lead, the bath being heated to the correct temperature and steel immersed in the bath for the determined length of time after which component (steel) is removed and allowed to cool to room temperature. Air tempering furnaces are very successfully employed for tempering. These furnaces are fully automatic and the hot air (heated by gas or electric means) is circulated around the parts to be tempered.
