ALLOY 20 NICKEL
ALLOY 20 NICKEL
Alloy 20 is a nickel-chromium-molybdenum alloy developed for applications involving sulfuric acid. Its corrosion resistance also finds other uses in the chemical, food, pharmaceutical, power generation and plastics industries. Alloy 20 nickel tubing resists pitting and chloride ion corrosion and its copper content protects it from sulfuric acid.
Typical applications include tanks, piping, heat exchangers, pumps, valves.
