How to deal with the deformation of stainless steel tensile parts: 

Considerable internal stress is stored in the material after cold working, and tensile will cause work hardening of the material. Annealing process is the process of removing internal stress, after the elimination of internal stress, material can produce plastic deformation, the trend is toward the unstretched state before the return, the amount of retraction and the size of the tensile residual stress, it should be related to the cold and hot deformation test, touch the deformation law of clear after annealing, stretching, reserve the allowance, ensure parts size requirements after annealing.
