HT ASTMA403 WP317L-S 6” SCH40S ASME B16.9 Heat No.77329
ASTM A403 WP317L is a molybdenum bearing, low carbon content “L” grade austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. ASTM A403 WP317 Pipe Fittings could be a altered adaptation of Stainless Steel 317L Pipe Fittings.
The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products.The low carbon provides resistance to sensitization during welding and other thermal processes.besides they are weldable.This kind of steel can be continuously exposed to temperatures of about 1500¡ãF without appreciable scaling.All ASTM A403 WP 317L Stainless Steel Pipe Fittings shall undergo heat-treatment.
