TP304H Stainless Steel Seamless Pipe

TP304H Stainless Steel Seamless PipeTP304H Stainless steel seamless pipe, also known as 1.4948 stainless steel seamless pipe, is an austenitic stainless steel pipe. It has excellent heat resistance in raised temperatures. ASTM A312 TP304H Stainless steel seamless pipe are widely used in pipeline construction, oil and chemical industry, nuclear technology, and boiler making industry. The increased carbon content delivers a greater tensile and yield strength. The austenitic structure of TP304H stainless steel also gives it excellent toughness, even down to cryogenic temperatures. We supply and manufacture TP304H stainless seamless pipe with a wide range of size, from 10.0mm to 1219mm. The wall thickness of TP304H seamless stainless steel pipe ranges from 0.5mm to 100mm. The common length of each pipe is 5.8m, 6.0m, 11.8m, 12m. The maximum length we produce is up to 18m. Sheye Metal can produce TP304H seamless stainless steel pipes in strict accordance with ASTM, EN, JIS, DIN standard to meet client’s different requirements. ASTM A312 TP304H Stainless steel seamless pipe is the most common product. TP304H stainless seamless pipes can be cut to size and pipe with polished finish it is also available. A lot of processing services, including punching, painting, beveling, chamfering are all available for us. With strong technical force, advanced equipment and skilled craftsmanship, Sheye Metal can manufacture TP304H seamless stainless steel pipe and good quality is guaranteed. For metal, we are serious.Specification of 304H 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 RolledDifferent Name 1.4948 Seamless Stainless Steel Pipe X6CrNi18-10 Seamless Stainless Steel Pipe UNS S30409 Seamless Stainless Steel PipeEnd PE(Plain End), BE(Beveled End), NPT, BW(Butt Weld End)Surface Aid Pickling, Polishing, BrushingStandard ASTM A312, ASTM A213, EN10216-5, DIN 17456, DIN 17458, JIS G3459, JIS G3463Theoretical Weight(kg/m) Weight/meter = (OD-WT)*WT*0.02491    Both OD and WT in mm.Note: OD is the specified outside diameter.WT is the specified wall thicknessStainless steel pipes shall be pickled free of scale.
