310 & 310S Stainless Steel Applications:

Chemical Processing

  • to contain hot concentrated acids and ammonia

Heavy Machinery

  • conveyor belts, burner parts, combustion chambers, refractory anchor bolts, oven linings

Food Processing

  • used in contact with hot acids

Magnetic Properties:

310 flat rolled stainless steel is a non-magnetic alloy that cannot be hardened by heat treatment.


Type 310/310S has forming capabilties similar to that of Type 304. It can be easily formed into most shapes.
