310S Stainless Steel Plate - AMS 5521

310S  is a highly alloyed austenitic stainless steel designed for elevated-temperature service. The high Cr and Ni contents enable the alloys to resist oxidation in continuous service at temperatures up to 1200°C, provided reducing sulfur gases are not present. In intermittent service, it can be used at temperatures up to 1030°C as it resists scaling and has a relatively low coefficient of expansion. This alloy has superior resistance in carburizing environments and is used for their high-temperature oxidation resistance in applications such as furnace parts, mufflers, radiant tubes, and ammonia converters.
