904L Stainless Steel Seamless Pipe

904L Stainless Steel Seamless Pipe

904L Stainless steel seamless pipe, also known as N08904 seamless stainless steel pipe, is a high-alloy austenitic stainless tube with a high molybdenum and additional copper content.

Product Details

904L Stainless steel seamless pipe, also known as N08904 seamless stainless steel pipe, is a high-alloy austenitic stainless tube with a high molybdenum and additional copper content.

With excellent corrosion resistance to sulfuric and phosphoric conditions, they are widely used in chemical plant, heat exchanger industry, cellulose industry, etc. 904L stainless steel seamless pipe are inventoried in diameter from 21.3mm to 323.9mm.

We have rich experiences in manufacturing such long 904L seamless tube as 11.8m, 12m, 18m. Sheye Metal provides a lot of processing services, including cutting to length, polishing surface, punching, painting, etc.

In some countries, 904L stainless steel seamless pipe is also called as UB6 stainless steel or 1.4539. With b technical force, advanced equipment and skilled craftsmanship.

Sheye Metal can manufacture UB6 stainless steel pipe and good quality is guaranteed. For metal, we are serious.
