Stainless steels are known as high-alloy steels. They are classified into ferritic, austenitic, and martensitic steels based on their crystalline structure.
Grade 310S stainless steel is superior than 304 or 309 stainless steel in most environments, because it has high nickel and chromium content. It has high corrosion resistance and strength in temperatures up to 1149°C (2100°F). The following datasheet gives more details about grade 310S stainless steel.
Welding
Grade 310S stainless steel can be welded using fusion or resistance welding techniques. Oxyacetylene welding method is not preferred for welding this alloy.
Hot Working
Grade 310S stainless steel can be hot worked after heating at 1177°C (2150°F). It should not be forged below 982°C (1800°F). It is rapidly cooled to increase the corrosion resistance.
Cold Working
Grade 310S stainless steel can be headed, upset, drawn, and stamped even though it has high work hardening rate. Annealing is performed after cold working in order to reduce internal stress.
Annealing
Grade 310S stainless steel is annealed at 1038-1121°C (1900-2050°F) followed by quenching in water.
Hardening
Grade 310S stainless steel does not react to heat treatment. Strength and hardness of this alloy can be increased by cold working.
The process flow of the Stainless Steel Square Bar production line: billet acceptance → heating → rolling → double scale cutting → cooling → cutting → inspection → packaging → measurement → warehousing.
