Properties

Type 310S stainless steel, like 309S, is best known for high temperature service. Both alloys work well up to 2000 degF, especially if oxidation resistance is required. 309 and 310S are considered to be 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 intergranular corrosion

Applications

Just like 309S, 310S is used by the environmental, chemical processing and refining industries. Some equipment made 310S includes: incinerators, furnaces, burners, kilns, annealing and carburizing boxes, combustion chambers, salt pots, thermo wells, gas turbines, retorts, flairs and equipment to handle sulfite liquors.
