TorqBolt stocks highly corrosion resistant Duplex Screws. Duplex (austenite-ferrite) stainless steel is 40-50% ferrite in annealed conditions. It has crevice cracking resistance even higher than those of 304, 316L 317L also it has yield strengths higher or almost double than those austenite steels. However, this steel cannot be used for temperatures above 600 Degrees Fahrenheit. Some of its applications include pressure vessel tanks, piping, and heat exchangers in chemical Industry, paper industry, and cargo tanks of shipping industries and mainly in biofuel plants.
