Product Description

Duplex S31803 Seamless Pipe

The ASTM A789 UNS S31803 tubing refers to seamless and welded tubing manufactured in accordance with ASTM A789/ASTM A1789M, which contains approximately 50% ferrite and 50% austenite. The stress corrosion resistance of ASTM A789 in neutral chloride solution and H2S is better than that of 304L, 316L austenitic stainless steel, and 18-5mo type duplex stainless steel. The UNS S31803 tubing is especially suitable for the temperature range of -50°F/+600°F. It may also be considered for applications beyond this temperature range, but there are some limitations, especially when applied to weld structures.
