Applications of Alloy Steel AISI 310 / AISI 310S / UNS S31000 / UNS S31008 / SAE 30310 / SAE 30310S:

Alloy 310 (UNS S31000) is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. Because of its high chromium and moderate nickel content, Alloy 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). Alloy 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. Alloy 310 can be easily welded and processed by standard shop fabrication practices. Alloy 310 and 310S Stainless Steel Fittings, Flanges, Tubes and Pipes are used in the environmental, chemical processing and refining industries. Some examples of equipment composed of 310 Stainless Steel include incinerators, furnaces, burners, kilns, annealing and carburizing boxes, combustion chambers, salt pots, thermo wells, gas turbines, retorts, flairs and equipment to handle sulfite liquors.

 

Properties of Alloy Steel AISI 310 / AISI 310S / UNS S31000 / UNS S31008 / SAE 30310 / SAE 30310S:

Alloy 310S, like 309S, is best known for high temperature service. Both alloys work well up to 2000 °F, especially if oxidation resistance is required. 309 and 310S are the premier high temperature performers among the common stainless grades available from our stock. High nickel and chromium content and a coarse grain structure result in:

• Improved resistance to cyclic oxidation
• Increased resistance to sulfidation
• Better high temperature strength
• Improved resistance to inter granular corrosion

310S stainless steel provides superior corrosion resistance properties against carburization, oxidation and other conditions. It is fabricated to offer excellent performance in the elevated temperature conditions on the industrial level that need high resistance to carburization and thermal cycling corrosion. It shows austenitic nature in the whole temperatures and doesn’t show embrittlement. The excellent strength and resistance to high temperature oxidation properties are purposeful in the commercial incinerators, kilns and food processing equipments.
