Parameters Of UNS S31400 Stainless Steel

The annealing treatment of 314 stainless steel is usually carried out in the temperature range of 1120°C (2048°F) to 1200°C (2192°F), followed by rapid cooling. The purpose of annealing treatment is to eliminate the residual stress of the material during processing, restore the grain structure of the material, and improve its toughness and ductility. After annealing, 314 stainless steel has better mechanical properties and oxidation resistance and is suitable for use in high temperature environments.
