Polished ASTM A179 UNS S31500 Cold Rolled Steel Plate
Polished ASTM A179/A790M UNS S31500 Sheet Super Duplex Stainless Steel
Specs: A179/A179M (UNS S31500) A 25Cr Duplex Stainless Steel
Alloy A179/A179M (UNS S31500) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.
General Properties
- Allo A179/A179M UNS 31500 is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.
- The impact strength is also high. Alloy A179/A179M UNS 31500 is not recommended for applications which require long exposures to temperatures above 570°F because of the risk of a reduction in toughness.
