Product Parameters

 

AISI 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.
AISI 310S stainless steel seamless tubes/pipes are used in environmental, chemical processing, and refining industries. Equipment made from this steel includes incinerators, furnaces, burners, kilns, annealing and carburizing boxes, combustion chambers, salt pots, thermowells, gas turbines, retorts, flairs, and sulfite liquor handling equipment.
