310S

Short Description:

Introduction 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. Chemical Compositio...

Fabrication and Heat Treatment

Machinability

Grade 310S stainless steel can be machined similar to that of grade 304 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.

Applications

Grade 310S stainless steel is used in the following applications:

Boiler baffles
Furnace components
Oven linings
Fire box sheets
Other high temperature containers.
