Product Description Qingdao Ironsteel International Trading Co., Ltd provide high quality, low priced Cold Rolled/Cold Drawn Seamless steel pipes. Our factory founded in 2002, 15 advanced production lines can make full range sizes of cold rolled seamless steel pipes(by carbon steel/alloy steel materials) . We haveour own testing labs, equipped with all necessary testing equipments for chemical analysis, water pressure testing, X-ray inspection, ultrasonic testing, eddy current inspection, tension testing, chemical testing, and so on. High precision cold drawn seamless steel tube identifies the precision steel pipe with high dimension precision (inside diameter and outside diameter). Good surface finish, excellent roundness and straightness, and uniform wall occurrence. It can be very popular in mechanical structure and hydraulic gym equipment. This cold rolled or cold drawn seamless steel tube can greatly lessen machining time, raise the product excellence.https://qdironsteel.en.made-in-china.com/product/svInuZCdSekx/China-DIN-ASTM-API-Standard-Tandem-Rolled-Hot-Rolled-Seamless-Carbon-Steel-Pipe-25mm-610mm.htmlPrecise Cold Rolled Seamless Steel Pipe by DIN, ANSI, JIS standard.OD: 8mm~315mmWall thickness: 0.8mm~30mmTolerance: +/-0.1mmTechnique: Cold drawing/Cold rollingStandard: ASME SA192/SA179, GB/T8162, GB/T8163, GB/T3639, DIN2391-2Steel material: 20#(AISI 1020/DIN1.0402 C22), 45#(ASTM 1045,DIN45), 20Cr, 40Cr, ST52, ST45, ST37.4, Q345B, etcDelivery state: BK, BKW, NBK, GBK, BKSUsage: widely used for mechanical processing, Automobile industry, hydraulic equipmentsAdvantages of our high precision seamless steel pipe:1. Smaller caliber2. Accept small qty order3. Good surface treatment4. The pipe with superior performance, suitable for mechanical makingIntroduction of delivery stateDesignationSymbolDescriptionCold finished (hard)BKTubes do not undergo heat treatment following the final cold forming and,thus, have a rather high resistance to deformationCold finished (soft)BKWThe final heat treatment is followed by cold drawing involving limited deformation.Appropriate further processing allows a certain degree of cold forming(e.g. bending expanding).Cold finished and stress-rellevedBKSHeat treatment is applled following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degreeAnnealedGBKThe last cold forming process is followed by annealing in a controlled atmosphereNormalizedNBKThe last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphereDifferent kinds of delivery condition, surface of pipe can be bright, galvanized, phosphating, etc.Preicision Seamless Tube Size ListOD (mm)Thickness (mm)OD (mm)Thickness (mm)OD (mm)Thickness (mm)OD (mm)Thickness (mm)Φ13.11.5-3Φ35.51.5-7Φ46.11.5-10Φ931.5-15Φ19.251.5-5Φ35.91.5-7Φ47.81.5-10Φ19-Φ1211.5-15Φ221.5-5Φ36.61.5-7Φ49.21.5-10Φ121-Φ2008.0-25Φ22.21.5-5Φ381.5-8Φ49.51.5-10Φ200-Φ31510-30Φ251.5-6Φ38.41.5-8Φ52.31.5-10 Φ26.31.5-6Φ401.5-10Φ53.81.5-10 Φ271.5-6Φ40.21.5-10Φ571.5-10 Φ281.5-6Φ40.91.5-10Φ591.5-10 Φ301.5-6Φ41.31.5-10Φ601.5-11 Φ30.251.5-6Φ41.61.5-10Φ62.51.5-11 Φ30.91.5-6Φ421.5-10Φ741.5-11 Φ311.5-7Φ431.5-10Φ751.5-11 Φ321.5-7Φ44.51.5-10Φ761.5-11 Φ351.5-7Φ45.81.5-10Φ891.5-15 Precise size controlling, make sure the tolerance no more than +/-0.1mmSize tolerance ODStandard toleranceSpecial toleranceOuter DiameterGB/T3639DIN2391EN10305O Dthickness4mm-20mm±0.10 mm±0.08 mm±0.08 mm±0.05mm±0.05mm20mm-30mm±0.10 mm±0.08 mm±0.08 mm±0.08 mm±0.08 mm31mm-40mm±0.15 mm±0.15 mm±0.15 mm±0.10 mm±0.08 mm41mm-60mm±0.20 mm±0.20 mm±0.20 mm±0.15 mm±0.15 mm61mm-80mm±0.30 mm±0.30 mm±0.30 mm±0.20 mm±0.20 mm81mm-120mm±0.45 mm±0.40 mm±0.40 mm±0.30 mm±0.30 mm Chemical Composition of seamless steel pipeMaterialChemical composition (%)CMnPSSiNiCu20#AISI 10200.17~0.230.35~0.65≤0.035≤0.0350.17~0.37≤0.3≤0.2545#ASTM1045, DIN450.42~0.50.5~0.8≤0.04≤0.0450.17~0.37≤0.25≤0.25Mechanical Properties of seamless steel pipeSteel materialTensile Strength MpaYield strength MpaElongation%HardnessStraightness20#≥510≥245≥25≤156HB0.3~1.045#≥647≥355≥16≤HRC620.3~1.0 Our factory takes more than 5 suare kilometers, 15 production lines can make different sizes cold rolled or cold drawn seamless pipes.Professional exporting team grarantee the top quality of packing and shipment service.FAQQ: What's your advantages1.
