Alpha Overseas is one of the distinguished manufacturers that offer Alloy 20 Pipes, which is a nickel–chromium–molybdenum alloy developed for applications involving sulphuric acid. Alloy 20 Tubes is an iron-base, austenitic alloy with excellent corrosion resistance to a number of different media and proves to be useful in a number of applications. Incoloy 20 Pipes is an austenitic, nickel-iron-chromium based super alloy with additions of Molybdenum and Copper which provide resistance to hostile environments, crevice corrosion and pitting. Incoloy 20 Tubes, which also includes molybdenum and copper, is popular in the production of gasoline, chemicals, pharmaceuticals, food, synthetic, solvents, and explosives materials. Alloy 20 Seamless Pipes exhibits exceptional corrosion resistance in chemical environments containing phosphoric acid, chlorides, sulphuric, and nitric acid. Alloy 20 Seamless Tubes is designed specifically to withstand sulphuric acid. Alloy 20 Welded Pipes is a columbium stabilized material that combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. Alloy 20 Welded Tubes is a super-austenitic stainless alloy developed for maximum corrosion resistance to sulphuric acid and other aggressive environments not suitable for typical austenitic grades.
