Norwich Steel & Engineering Co. is one of the well-known distributors of Alloy 20 Round Bars, which has practical immunity to chloride stress corrosion cracking. Alloy 20 Rods is popular in the production of explosives, chemicals, gasoline, solvents, etc. The addition of copper and molybdenum in Alloy 20 Square Bars provides pitting and crevice corrosion, along with resistance to hostile environments. Alloy 20 Flat Bars seems to fall in the range of nickel and stainless classes as it covers features of both. Alloy 20 Threaded Bars is an austenitic stainless steel developed for applications involving sulfuric acid. Alloy 20 Hollow Bars has excellent general corrosion resistance to sulfuric acid. After hot functioning, annealing of Alloy 20 Hexagonal Bars can be done by heating up to 1725 ° F and 1850 ° F for minimum of thirty mins per inch of width trailed by quench of water. Inter - granular corrosion (IGC) in Alloy 20 Hex Bars, as well recognized as inter - granular attack (IGA), is quite a form of erosion where limits of crystallites of material are additional vulnerable to erosion.
