Alloy 20｜Carpenter 20Cb3｜N08020｜Pipe and Tube
Alloy 20 (Carpenter 20Cb3, N08020), The Cr content is usually 19.0-21.0%, and the nickel content is 32.0-38.0%. It is a nickel base alloy containing molybdenum and copper, and has good hot working and cold working properties. Corrosion resistant alloys with many excellent properties have good resistance to oxidizing and moderately reducing corrosion, excellent resistance to stress corrosion cracking and good resistance to local corrosion. They have satisfactory corrosion resistance in many chemical process media.
Its excellent resistance to sulfuric acid corrosion; The resistance to chloride stress corrosion, pitting corrosion, and crack corrosion is also strong in environments with phosphoric acid, nitric acid, and chloride. It is widely used in chemistry, food, medicine, power generation, and plastic industries.
