ASTM A240 F904L /UNS N08904 AWWA C207 SO FF , STAINLESS STEEL FLANGES
We are one of the biggest projects pipeline products supplier in China , Our products contain steel pipe/tube,fittings, flanges. With development more than 20 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.
Scope:
ASTM A240 covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. The steel shall conform to the requirements as to chemical composition specified. The material shall conform to the mechanical properties specified.
Our Grade 904L SS Flanges stands up tremendously well to chlorides in the atmosphere for crevice corrosion andlow pitting, in addition to stress corrosion cracking. These Grade 904L Stainless Steel Flanges merges copper andmolybdenum content in the company of iron content for extremelyaugmented resistance to reducing acids such as sulphuric acid. Made up from top quality of raw materials, these products comply with all industrial quality standards.With several sizes, lengths and dimensional specifications, these UNS N08904 Flangesare also customized as per customer requirements at market leading prices.
