Nickel Alloy 20 Summary:

Alloy 20 is a nickel-iron-chromium based, austenitic alloy with excellent corrosion resistance in chemical environments containing sulfuric acid and many other aggressive media. This alloy is stabilized with niobium to resist intergranular corrosion. Its corrosion resistance also finds other uses in the chemical, petrochemical, power generation, and plastics industries. Alloy 20 resists pitting and chloride ion corrosion, better than 304 stainless steel and on par with 316L stainless steel. Its copper content protects it from sulfuric acid. Alloy 20 is often chosen to solve stress corrosion cracking problems, which may occur with 316L stainless.

Nickel Alloy 20 Valve Futures:

Alloy 20 steel is a solution for stress corrosion cracking that can occur when stainless steel is introduced to chloride solutions. We supply Alloy 20 steel for a variety of applications and will help in determining the precise amount for your current project. Alloy 20 can be used for a wide variety of applications including control valves, pressure relief valves, and centrifugal pumps. It is composed of carbon, chromium, copper, iron, manganese, molybdenum, nickel, phosphorous, silicon, and sulfur.

Nickel Alloy 20 Applications:

Although originally designed for use in sulfuric acid related industries, Alloy 20 is now a popular choice for a wide variety of industries including the chemical, food, pharmaceutical, and plastics industries. In addition, this superalloy is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping. Carpenter 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication.
