Description
S32205 Duplex Steel Bar Rod
Bar Profile
Compared with 316L and 317L austenitic stainless steel, the 2205 alloy has superior performance in resisting plaque and crevice corrosion. It has high corrosion resistance and thermal expansion compared with austenite. Lower coefficient and higher thermal conductivity. 2205 alloy is especially suitable for use in the temperature range of -50°F/+600°F. It can also be used for lower temperatures under severe restrictions (especially for welded structures). It has high strength, good impact toughness and Good overall and local resistance to stress corrosion.
