摘要：

Duplex stainless steels in wrought or cast form, when they reach the user, consist of a microstructure of approximately 50% austenite and 50% ferrite. This mix of phases imparts very desirable properties to the material over a useful service temperature range from as low as minus 50 degree F ( minus 46 degree C) to as high as 500 degree F (260 degree C), notably: yield strength nearly double that of wrought austenitic stainless steel, ductility and toughness approaching that of wrought austenitic stainless steel, and resistance to chloride stress corrosion cracking approaching that of wrought ferritic stainless steel.
