ASTM A182 F317 F317L Blind RF SS Forged Flange Bridas
YUHONG Group offers ASTM A182/ASME SA182 F317 / F317L Stainless Steel Forged 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 F317/F317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance, stronger chemical corrosion resistance.Therefore, this steel F317/F317L is widely used in petroleum, chemical, pharmaceutical, food and other fields.
