6/17/2023 0 Comments Density of steel![]() SS304 is suitable for cold working operations including cold heading, cold drawing, cold extrusion and cold riveting, but it is more difficult than cold working of carbon steel. When the weldment is not suitable for full annealing, the residual stress of SS 304 grade stainless steel can be moderately reduced below 450 ☌ (840 ☏). HardeningĪISI SAE ASTM 304 stainless steel can’t be hardened by heat treatment but can be hardened by cold working. Type 304 stainless steel typical forging temperature is 925-1260 ☌ (1700-2300 ☏). Type 304 stainless steel annealing temperature range is 1010-1065 ☌ (1850-1950 ☏),1040 ☌ (1900 ☏) is recommended and then rapidly cooled.īefore annealing, the surface should be carefully cleaned, and to prevent the formation of an oxide layer during the annealing process, vacuum, hydrogen or inert gas protection must be used. The following is the heat treating 304 stainless steel, such as annealing, forging, hardening, stress relieving, etc.
