904L Stainless Steel Seamless Pipe

904L Stainless Steel Seamless Pipe904L Stainless steel seamless pipe, also known as N08904 seamless stainless steel pipe or 904L stainless steel seamless 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, 904L stainless steel seamless pipes are widely used in chemical plant, heat exchanger industry, cellulose industry, etc. 904L Stainless steel seamless tubes 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 is also called as UB6 stainless steel or 1.4539. With Strong 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.Specification of 904L Stainless Steel Seamless Pipe Size OD: 10.0 ~ 1219mm; WT: 0.5 ~ 100mm; Length: 5.8m, 6m, 11.8m, 12m, Max.18mProcess Seamless, Cold Drawn, Cold Rolled, Hot RolledEnd PE(Plain End), BE(Beveled End), NPT, BW(Butt Weld End)Surface Aid Pickling, Polishing, BrushingStandard ASTM B677Theoretical Weight(kg/m) Weight/meter = (OD-WT)*WT*0.02507    Both OD and WT in mm.Materials and Manufacture 904L Stainless steel seamless pipe shall be supplied in the solution-treated condition.
