Purpose of tempering
Reduce internal stress and brittleness. Quenched steel strips have great stress and brittleness. If they are not tempered in time, they will often deform or even crack.
Adjust the mechanical properties of stainless steel. After quenching, the steel strip has high hardness and brittleness. In order to meet the different performance requirements of various workpieces, the hardness, strength, plasticity and toughness can be adjusted by tempering.
Stable steel strip size. Tempering can stabilize the metallographic structure to ensure that it will no longer deform during subsequent use.
Improve the cutting performance of stainless steel.
