J & J Alloys is an industry leading manufacturer of nickel alloy fitting and flanges with a wide array of standard as well as specialty products we are capable of producing.
Alloy 20 is one of the so-called “Super” stainless steels that was designed for maximum resistance to acid attack. Its nickel, chromium, molybdenum and copper content contribute to its overall resistance to chlorideon stress corrosion cracking and general pitting attack. The alloy is stabilized with columbium to minimize carbide precipitation during welding.
