ASTM A182 F347 WN RF Stainless Steel Flanges , Bridas
YUHONG Group can offer ASTM A182 F347 welding neck RF stainless steel flanges / bridas, and our products sell more than 70 countries up to now.
ASTM A182 --- 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.
F347 is a high temperature stainless steel with good corrosion resistance and high temperature strength. It can adjust its wear resistance and corrosion resistance by adding alloy elements to meet the needs of specific application scenarios. It has many excellent properties, such as corrosion resistance, high temperature resistance, oxidation resistance, tensile resistance, easy processing, etc., so it is widely used in many fields.
