304 25mm 0.71mm Thickness Metal ASTM ERW Polished Decorative Stainless Steel Round Welded Pipe and Tube Pipes Tubes Tubing

Stainless Steel Pipe&Tube is a kind of hollow long round/square steel, stainless steel pipe is divided into seamless steel pipe and welded steel pipe .mainly used in petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and other industrial pipeline and mechanical structure parts.In addition, in bending, torsional strength at the same time, relatively light weight, so also widely used in the manufacture of mechanical parts and engineering structures..It is also commonly used in the production of various conventional weapons, barrels, shells etc.  Stainless Steel Pipe&TubeStainless steel pipe is a kind of high toughness pipe with excellent shock resistance. Its low temperature embrittlementtemperature is very low, can be used safely in the temperature range of -60~100ºC, in winter construction, due to the good impactresistance of the material, it is not easy to crack the pipeline, the pipeline is deformed by external impact and does not affectthe pipeline operation, and the corrosion resistance level is strong and efficient to ensure the pipeline safety.Product DescriptionProduct NameStainless Steel Seamless Pipe/TubeMaterial1.Mainly:201, 202, 304, 304L, 304H, 316, 316L,316Ti,2205, 330, 630, 660, 409L, 321, 310S, 410, 416, 410S, 430, 347H, 2Cr13, 3Cr13etc2.300series:301,302,303,304,304L,309,309s,310,310S,316,316L,316Ti,317L,321,347 3.200series:201,202,202cu,2044.400series:409,409L,410,420,430,431,439,440,441,444 5.Others:2205,2507,2906,330,660,630,631,17-4ph,17-7ph, S318039 904L,etc6.Duplexstainless Steel: S22053,S25073,S22253,S31803,S32205, S323047.Special Stainless Steel:904L,347/347H,317/317L,316Ti,254MoWall Thickness0.01-50mm,or customizedDiameter1mm-4501mm-4500mm1mm-4500mm0mm,or customizedShapeRound, Square, Rectangular, OvalSurfacePrimary, Bright Polished, Hairline, MirrorColorGolden, Champagne gold, Rose gold, Brown, Bronze, Brass, Black, etc.StandardASTM, JIS, GB, AISI, DIN, BS,EN,ETC,etc.CertificationsISO 9001 BV SGSPackingIndustry standard packaging or according to client's requirementMOQ3 TONS,can be customized according to your requirements.Payment Terms20%T/T in advance, the balance against the B/L copyDelivery timeFast delievery in 7 days,up to order quantityApplicationUsed in the production of electrical components, connectors, radiators,Conductive base materials,automobile water tanks, heat sinks, cylinder fins, etc.  About Stainless SteelStainless Steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the passive layer. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.Stainless steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced formability and increased corrosion resistance.GradeCSiMnPSNiCrMo201≤0.15≤0.755.5-7.5≤0.06≤ 0.033.5-5.516.0-18.0-301≤0.15≤1.0≤2.0≤0.045≤ 0.036.0-8.016.0-18.0-304≤0.08≤1.0≤2.0≤0.045≤ 0.038.0-10.518.0-20.0-304L≤0.03≤1.0≤2.0≤0.035≤ 0.039.0-13.018.0-20.0-316≤0.08≤1.0≤2.0≤0.045≤ 0.0310.0-14.016.0-18.02.0-3.0316L≤0.03≤1.0≤2.0≤0.045≤ 0.0312.0-15.016.0-18.02.0-3.0321≤0.08≤1.0≤2.0≤0.035≤ 0.039.01317.0-1 9.0-410≤0.15≤1.0≤1.0≤0.035≤ 0.03-11.5-13.5-430≤0.12≤0.75≤1.0≤0.040≤ 0.03≤0.6016.0-18.0-ItmeSurface finishingSurface finishing methodsMain applicationNO.1HRHeat treatment after hot rolling, pickling, or with treatmentFor without the purpose of the surface glossNO.2DWithout the SPMMethod of heat treatment after cold rolling, pickling surface roller with wool or eventually a light rolling a matte surface processingGeneral materials,building materials.NO.2BAfter SPMGiving No.2 processing materials appropriate method of cold light sheenGeneral materials, building materials ( most of the goods are processed )BABright annealedBright heat treatment after cold rolling , in order to be more shiny, cold light effectAutomotive parts, home appliances, vehicles, medical equipment, food equipmentNO.3Shiny, coarse grain processingThe NO.2D or NO.2B processing timber No. 100-120 polishing abrasive grinding beltBuilding materials, kitchen suppliesNO.4After CPLThe NO.2D or NO.2B processing timber No. 150-180 polishing abrasive grinding beltBuilding materials, kitchen supplies, vehicles, medical equipment, food equipment240#Grinding of fine linesThe NO.2D or NO.2B processing timber 240 polishing abrasive grinding beltKitchen appliances320#More than 240 lines of grindingThe NO.2D or NO.2B processing timber 320 polishing abrasive grinding beltKitchen appliances400#Close to BA lusterThe MO.2B timber 400 polishing wheel polishing methodBuilding materials, kitchen utensilsHL(hair lines)Polishing line having a long continuous processingIn a suitable size ( usually mostly No. 150-240 grit ) abrasive tape for as long as the hair, having a continuous processing method of polishing li
