Alloy 20, also known as Carpenter®20 and Incoloy®20, is an austenitic nickel-iron-chromium alloy. The super alloy, which also contains copper and molybdenum, is popular in the production of gasoline, solvents, explosives, chemicals, pharmaceuticals, food and synthetic materials. It provides users with a variety of benefits including: excellent corrosion resistance, crevice corrosion and pitting; Suitable for sulfuric acid, phosphoric acid and nitric acid; Easy to manufacture and improve mechanical properties;
Alloy 20 meets or exceeds various industry standards, including a variety of ASTM, ASME, ISO and DIN standards. TIG, MIG and SAW welds can be used for alloy 20 and can be formed by hot and cold processing.
Alloy 20 has a unique chemical composition: iron balance is 31-44%; 32.5-35% nickel; Cr (19-21%; Copper by 3-4%; Mo 2-3%;
There is some disagreement as to whether alloy 20 is a nickel or stainless steel alloy due to its high nickel content (32-38%). No matter what side of the discussion you are on, it is clear that Alloy 20 is the best choice for a variety of industries and applications.
