DUPLEX 2205 STAINLESS STEEL UNS S31803, UNS S32205, ASTM A182, ASTM
A276, ASTM A479
Duplex 2205 Stainless Steel is a nitrogen-enhanced duplex used in applications requiring high
strength and excellent corrosion resistance. It is designed to
combine improved resistance to stress corrosion cracking, pitting
and crevice corrosion. Duplex 2205 provides nearly double the
corrosion resistance typical in other austenitic stainless steels.
Best Stainless supplies Duplex 2205 SS for a variety of industries
including oil & gas, petrochemical, marine and pulp & page
factories. Best stainless also offers Duplex 2507.
