ASTM B677 TP904L UNS N08904 Stainless Steel Seamless Pipe
ASTM B677 TP904L UNS N08904 Stainless Steel Seamless Pipe
We are one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. 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.
The higher contents of chromium and molybdenum used to alloy the SB 677 904L Stainless Steel Pipe ensures that it has excellent performance, especially in corrosive environments. Into the bargain of having good resistance to dilute sulfuric acid, the 904L Welded Pipe indicates good resistance to other inorganic acids as well as many organic acids. For instance, the ASTM B677 specified SS 904L Tube has remarkable resistance properties to hot phosphoric acid. Produced under this specification, the ASTM B677 TP 904L could be produced either in a seamless, hot finished or cold worked condition. Typically, the tubes manufactured from ASTM B677 UNS N08904 grade are designed to be used for general corrosive service.
