ASME SA182 F317L WN RF Stainless Steel SMLS Flange , Bridas
YUHONG Group offers ASTM A182/ASME SA182 F317L-S Stainless Steel Flanges.
This specification covers forged low alloy and stainless steel piping components for use in pressure systems. Included are flanges, fittings, valves, and similar parts to specified dimensions or to dimensional standards.
Compared with conventional stainless steel, A182/SA182 F317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance, and stronger chemical corrosion resistance.And it is widely used in petroleum, chemical, pharmaceutical, food and other fields.
