347 SS is a heat and corrosion resisting alloy stabilized by the addition of columbium and titanium. It is superior for welded construction used in both severely corrosive and elevated temperatures between 800-1500°F. Type 347 is nonmagnetic when annealed, and slightly magnetic when cold worked. Typically used for aircraft or jet engine parts, pressure vessels, fire walls, and elevated temperature chemical handling equipment.
