Simulated heat of heat affected zone and researched a mechanical properties in used the SS400 and the STS304. As the result, mechanical properties of steel that make drawing decreased because of residual stress by strain hardening due to the heat-simulated temperature rises, but by the temperature rising in materials that have done heat-simulated after annealing, the mechanical properties ware improved.
