ASTM A403 WP310S-S， UNS S31008 Stainless Steel Buttweld Pipe Fittings 90 Deg Elbow B16.9
ASTM A403 WP310S stainless steel pipe elbow contains material which is the low carbon version of stainless steel 310. SS310S is less prone to sensitization in service and embrittlement. Both Stainless steel 310 and Stainless steel 310s are forged in the temperature range of 975 to 1050 °C. SS310S is used mainly for ease of fabrication and is also corrosion resistant. Stainless steel 310 and stainless steel 310S are identical only the major difference is of carbon content that reduces carbide precipitation and also helps in improving weldability. 310S stainless steel pipe fittings have oxidation resistance up to 2000° F， having moderate strength at higher temperature. It also resists hot corrosion till an extent.
