Alloy 20 Nickel Chromium Stainless Steel
Alloy 20 is a nickel–chromium–molybdenum stainless steel alloy great for applications involving sulfuric acid. Other uses include the chemical, food, pharmaceutical, power generation, and plastics industries due to its corrosion resistance. Alloy 20 resists chloride ion corrosion and its copper content protects it from sulfuric acid. Alloy 20 is not a stainless steel but a nickel alloy (ASTM).
Provides excellent resistance to stress-corrosion cracking and to hot sulfuric acid; weldable, machinable and cold formable; best corrosion resistance of all stainless steel grades.
Approximately 34% nickel, 20% chromium.
