TP316H Stainless Steel Seamless Pipe

TP316H Stainless Steel Seamless Pipe316H Stainless steel seamless pipe, also known as 1.4919 stainless steel seamless pipe, is an austenitic chromium-nickel-molybdenum stainless tube, in addition with nitrogen and boron. TP316H stainless steel seamless pipes are intended for service at temperatures where creep and stress rupture properties are important. 1.4919 stainless steel seamless pipes have a very good resistance to raised temperature. Comparing with 316 stainless, 316H stainless has many advantages, such as heat resistance, acid resistance and corrosion resistance. 316H stainless steel is a higher carbon variant of 316 stainless steel, which makes it more suitable for high temperature environment. The increased carbon content delivers a greater tensile and yield strength. The austenitic structure of 316H stainless steel also gives it excellent toughness, even down to cryogenic temperatures. We supply and manufacture 316H stainless seamless pipe with a wide range of size, from 10.0mm to 1219mm. The wall thickness of 316H 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 TP316H seamless stainless steel pipes in strict accordance with ASTM, EN, JIS, DIN standard to meet client’s different requirements. TP316H stainless seamless pipes can be cut to size and pipe with polished finish it is also available. Sheye Metal owns advanced production equipments and testing instruments. We can inspect our seamless pipes with 16 channel ultrasonic testing machine, 8 channel ultrasonic flaw detector, double channel ultrasonic flaw detector, eddy current flaw detector, hydrostatic testing machine, or X-ray detector. 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 316H seamless stainless steel pipe and good quality is guaranteed. For metal, we are serious.Specification of 316H 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 1.4919 Seamless Stainless Steel Pipe X6CrNiMoB17-12-2 Seamless Stainless Steel Pipe UNS S31609 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*0.02507    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.
