UNS N08330
330 SS is primarily an alloy to endure high heat and is most useful between 1500- 2150°F. It is used for its greater resistance to heat and thermal shock than other stainless steel grades. It is a corrosion resisting steel that can be used in sulfur controlling oxidizing gases up to 1900°F. In reducing or neutral sulfur free atmospheres it can be used up to 2150°F. Type 330 is nonmagnetic when annealed or cold worked. Typically used for annealing parts, carburizing boxes, and furnace parts.
