LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
310 (UNS S31000) is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. The alloy resists oxidation up to 2010oF (1100oC) under mildly cyclic conditions.
Because of its high chromium and moderate nickel content, 310 is resistant to sulfidation and can also be used in moderately carburizing atmospheres.
The more severe carburizing atmospheres of thermal process equipment usually require nickel alloys such as 330 (UNS N08330). 310 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced. Alloy 310 also finds usage in cryogenic applications with low magnetic permeability and toughness down to -450oF (-268oC). When heated between 1202 - 1742oF (650 - 950oC) the alloy is subject to sigma phase precipitation. A solution annealing treatment at 2012 - 2102oF (1100 - 1150oC) will restore a degree of toughness.
310S (UNS S31008) is the low carbon version of the alloy. It is utilized for ease of fabrication. 310H (UNS S31009) is a high carbon modification developed for enhanced creep resistance. In most instances the grain size and carbon content of the plate can meet both the 310S and 310H requirements.

310S can be easily welded and processed by standard shop fabrication practices.
Heat uniformly at 1742 - 2192°F (950 - 1200°C). After hot forming a final anneal at 1832 - 2101°F (1000 - 1150°C) followed by rapid quenching is recommended.
The alloy is quite ductile and forms in a manner very similar to 316. Cold forming of pieces with long-term exposure to high temperatures is not recommended since the alloy is subject to carbide precipitation and sigma phase precipitants.
310S can be readily welded by most standard processes including TIG, PLASMA, MIG, SMAW, SAW and FCAW.
