The hardness and tensile strength in austenitic stainless steel can be increased by

Answer 1

By hardening and cold working...

Hope it helps....

Answer 2

A rare property of annealed austenitic stainless steels is that the yield strength is only 40-45% of the tensile strength. However, yield strength can be increased through a small amount of cold-work, thereby simultaneously increasing tensile strength. In severely cold-worked materials, such as strips or spring temper wires, yield strength is usually 80-95% of the tensile strength.
