YUHONG Group can offer ASTM A182 F904L slip-on 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.

 

SS 904L is a super austenitic stainless steel(UNS: N08904; EN: 1.4539), which is used for various high corrosion resistance environment design. and it is a high-alloy austenitic stainless steel with low carbon content. It has good corrosion resistance in dilute sulfuric acid and is specially designed for corrosion conditions. Designed for harsh environments. With high chromium content and sufficient nickel content, the addition of copper makes it have strong acid resistance, pitting resistance is slightly better than other steel types, has good machinability and weldability, and can be used for pressure container
