Incoloy 20

Alloy 20 is a nickel-iron-chromium austenitic high temperature alloy containing niobium, molybdenum and copper. It can also be called alloy 20 stainless steel. Among them, niobium can resist intergranular corrosion. The combination of various elements can make it in sulfuric acid and phosphoric acid,nitric acid has the greatest degree of corrosion resistance.Incoloy 20 can be available in bar, Pipe, Forging, Plate, Fasteners, Coil, Wire, Fitting, etc.

Overview of Incoloy Alloy 20

Other common names: UNS N08020, W.Nr.2.4660, Carpenter 20

Alloy 20 is a nickel-iron-chromium austenitic high-temperature alloy containing niobium, molybdenum, and copper. It can also be called alloy 20 stainless steel. Among them, niobium can resist intergranular corrosion, and the combination of various elements can make it suitable for sulfuric acid and phosphoric acid. It maintains the greatest degree of corrosion resistance in nitric acid and 20% to 40% sulfuric acid boiling. The alloy has good resistance to pitting and crevice corrosion. It is usually used to solve chlorine However, it is not recommended to use it at temperatures above 1000°F. Alloy 20 can be formed by hot and cold processing using traditional methods. Niobium enhances stability, minimizes carbide precipitation during welding, and allows the welded structure to be used in corrosive environments, usually without post-weld heat treatment. The alloy was originally designed for use in the sulfuric acid industry, but due to its combination of excellent corrosion resistance, high mechanical properties, and good processability, it has now been widely used in the chemical, petrochemical, food, power generation, and plastic industries.
