AISI 4140 42CrMo Carbon Steel Bar High Strength Hot Rolled Rod Round Bar

Product DescriptionCarbon rod is non-metallic product, it has high temperature resistance, good electrical conductivity, not easy to break properties, suitable for cutting metal into the required shape. Because of the high temperature of the carbon rod, it is easy to conduct electricity and has good chemical stability. It has been widely used in national defense, machinery, metallurgy, chemical industry, casting, non-ferrous alloy, lightening and other fields, especially black carbon rod, also used in ceramics, semiconductors, medicine, environmental protection, laboratory analysis and other fields, has become the most widely used non-metallic materials.  Steel GradeQ195,Q235,Q345,45#, S20C, SAE1010,SAE1020.SAE1045,EN8,EN 19fC45,CK45,SS400 etcStandardASTM A615Gr40/60,BSS4449 Gr460B,500B etcDiameter5.5-250 mmLength3000mm-12000mm or as client's requestStraightness3mm/M maxTolerance+0.5mm/-0(dia),+5mm/-0(L)MOQ5 tonsHeat treatmentNormalized / Annealed / Quenched / temperedSurfaceblack,mill,polished,brush,etcTestUltrasonic test according to SEP 1921-84 G3 C/cApplicationWidely used in construction industry for reinforcing concret(Express way; office building, Bridge etc) Trasportation By sea(20' 40' container), parts of larger cross-sections, crankshafts, gears.PackagingExport standard, seaworthyDelivery time10-20 days after confirmed orderContainer size20ft GP:5898mm(Length)x2352mm(Width)x2393mm(High)40ft GP:12032mm(Length)x2352mm(Width)x2393mm(High)40ft HC:12032mm(Length)x2352mm(Width)x2698mm(High)Item TypeDiameter (MM)LengthRound Bar8-4006/9/12m or follow client's requirment.Steel Wire Rod5.5-34CoilSteel Rebar5.5-40Cut to length or CoilCategoryGradesSizesStandardCarbon structure steelQ195,Q215,Q235,Q27516mm-250mmGB/T700-2006Low alloy high strength structure steelQ295,Q345,Q390,Q420, Q46016mm-250mmGB/T1591-2008Prime Carbon structure steel10#, 20#, 35#, 45#, 60#, 20Mn,65Mn,B2, B3,JM20, SH45,S45C,C4516mm-250mmGB/T699-1999Alloy structure steel30Mn2,40Mn2,27SiMn, 42Crmo, 20Cc40Cr,20CrMo, 35CrMo,20CrMnTi, 30CrMnTi,20MnVB, 20MnTiBf 45MnV 20CrNiMo, Q345B, 35MnBM,40MnB,36Mn2V16mm-250mmGB/T3077-1999Spring Steel65Mn,60Si2Mn, 50CrVA16mm-250mmGB/T1222-84Bearing SteelGCr15tGCr15GD,55SiMoV16mm-250mmGB/T18254-2002Structural steels subject to end-quench hardenability requirements20CrMnTi,30CrMnTi, 20Cr, 40Crf30CrMo,42CrMoA,27SiMn, 40Mn2H, 20CrNiMo, 40Mn2,q345b,35MnBM, 40MnB,45MnV.16mm-250mmGB/T5216-2004Oil wells structural steel37Mn5,36Mn2V16mm-250mmQ/LYS248-2007Marine anchor chain steelCM490,CM690,M30Mn216mm-250mmYB/T66-1987 GB/T18669-2002     Detailed Photos Chemical CompositionCSiMnSPCrNiCuMo0.38~0.45%0.17~0.37%0.50~0.80%≤0.035%≤0.035%0.90~1.20%≤0.30%≤0.30%0.15~0.25%CertificationsPackaging & ShippingCompany ProfileJiangsu Ruilaibo Special Steel Co., Ltd is located in Wuxi, Jiangsu, which is leading high-end supporting service enterprise in the field of carbon steel, tinplate, galvanized steel, stainless steel material in China.
