JIS Stainless Seamless Pipe SUS310STB

Stainless steel 310/310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000F. Its high chromium and nickel contents provide comparable corrosion resistance, superior resistance to oxidation and the retention of a larger fraction of room temperature strength than the common austenitic alloys like Type 304. Stainless 310 is often used at cryogenic temperatures, with excellent toughness to -450° F, and low magnetic permeability.
Grade 310, combining excellent high temperature properties with good ductility and weld ability, is designed for high temperature service. It resists oxidation in continuous service at temperatures up to 1150° C provided reducing sulphur gases are not present. It is also used for intermittent service at temperatures up to 1040° C.
Grade 310S (UNS S31008) is used when the application environment involves moist corrodents in a temperature range lower than that which is normally considered "high temperature" service. The lower carbon content of 310S does reduce its high temperature strength compared to 310. Like other austenitic grades these have excellent toughness, even down to cryogenic temperatures, although other grades are normally used in this environment.
Grade 310L (and proprietary versions of this grade), is a 0.03% maximum carbon version of 310, sometimes used for very specific corrosive environments, such as urea production.
Characteristics of 310/310S Stainless
Oxidation resistance to 2000° F
Moderate strength at high temperature
Resistance to hot corrosion
Strength and toughness at cryogenic temperatures
Fabrication with Stainless 310/310S
Type 310/310S is readily fabricated by standard commercial procedures. In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly.
Type 310/310S can be welded using all of the common welding processes.
