Mechanical Properties of 304 Stainless Steel Pipe / Tube

Heat Treatment of 304 Stainless Steel

304 stainless steel is an austenitic stainless steel and cannot be hardened by heat treatment. Heat treatment is mainly used to:

• Solution Annealing: Heat to 1010 – 1120 °C, then rapidly cool (water quenching)

• Stress Relief Annealing: Used to relieve work-hardening or welding stress
