The structure of ASTM A789 S31803 stainless steel pipe consists of an austenite pool surrounded by a continuous ferrite phase, containing approximately 40-50% ferrite in the annealed condition.
S31803 duplex stainless steel pipe combines the high strength of ferritic alloys with resistance to chloride stress corrosion, and is superior to 316L or 317L austenitic stainless steel pipes in almost all corrosive media.
The use of S31803 stainless steel pipe should be limited to temperatures below 600°F (about 316°C), as prolonged high temperature exposure may embrittle S31803 stainless steel. Widely used in chemical, petroleum, natural gas, marine engineering, food processing and other fields.
