products : { 309 - Alloy 309 stainless is best known for high temperature service. }

Properties

Alloy 309S is best known for high temperature service. This alloy works well up to 2000 degF, especially if oxidation resistance is required. 309 and 310 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

Alloy 309S is used by the environmental, chemical processing and refining industries. Some equipment made with 309 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.
