Description

ASTM A789/ASME SA789 UNS S31803/1.4462 DUPLEX STAINLESS STEEL SEAMLESS TUBE

Overview:

The ASTM A789 UNS S31803 tubing refers to seamless and welded tubing manufactured in accordance with ASTM A789/ASTM A789M, 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.

The ASTM A789/A789M UNS 31803 tubes shall be made by the seamless or welded process with no filler metal added. It shall be quenched in cool air or water rapidly to a temperature of 1800°F[980°C]-1900°F[1040°C]. For seamless tubes, as an alternative to final heat treatment in a continuous furnace or batch-type furnace, while the tube temperature is not lower than the specified minimum solution treatment temperature, tubes may be immediately quenched in water or rapidly cooled by other means.
