Detailed PhotosStandard: ASTM A519material : 4130/4140Advantage: Alloy steel round 4140 tubing metric is normally used for heavy-duty industrial applications. Also referred to as Chromoly steel, 4140 round tube is known for strength, resistance to fracturing, abrasion, and impact in high-stress applications. Description: 4140/42 and 4130 Mechanical Tubing are medium carbon alloy grades, which are widely used for many general-purpose applications that require high tensile strength and toughness. The addition of chromium and molybdenum as alloying elements, combined with heat treatment, provides the combined advantage of hardness, ductility, and strength.Delivery Condition:Cold drawn/hard (+C) (BK)Cold drawn/soft (+LC) (BKW)Cold drawn and stress relieved (+SR) (BKS)Annealed (+A) (GBK)Normalized (+N) (NBK)Quenched and Tempered (QT) ApplicationCommercial aircraft, aircraft engine mountsMilitary aircraftAutomotiveMachine toolsHydraulic toolsAuto racingAerospaceOil and gas industries - as forged valve bodies and pumpsAgricultural and defense industries etc Standard Material Chemical Composition(%)   Standard Steel Grade C Si Mn P S Cr Mo ASTM A519 4130/30CrMo 0.28-0.33 0.15-0.35 0.40-0.60 ≤0.04 ≤0.04 0.8-1.1 0.15-0.25 4140/42CrMo 0.38-0.43 0.15-0.35 0.75-1 ≤0.04 ≤0.04 0.8-1.1 0.15-0.25   Mechanical Performance CW SR A N RM Tensile Strength(Mpa)Min A Elongation(%)Mn RM Tensile Strength(Mpa)Min A Elongation(%)Mn RM Tensile Strength(Mpa)Min Rel Yield Strength(Mpa)Min A Elongation(%)Mn RM Tensile Strength(Mpa)Min Rel Yield Strength(Mpa)Min A Elongation(%)Mn - - 724 10 517 379 30 621 441 20 - - 855 10 552 414 25 855 621 20 Equivalent Material referance: GB TOCT ASTM BS JIS NF DIN 10F   1010 040A10   XC10   10 10 10,101,012 045M10 S10C XC10 C10,CK10 20 20 1020 050A20 S20C XC18 C22,CK22 45 45 1045 080M46 S45C XC45 C45,CK45 30CrMo 30XM 4130 1717COS110 SCM420 30CD4   42CrMo   4140 708A42   42CD4 42CrMo4       708M40       35CrMo 35XM 4135 708A37 SCM3 35CD4 34CrMo4 Manufacture ProcessCompany Profile Chewit International Chewit international Located in zhangjiagang city which is along The Yangtze Golden Channel the junction of River and Coast Economic Belt. It owns an excellent geographic position, as it is close to Nanjing city in the north, adjacent to Suzhou and Wuxi cities in the south, next to Shanghai international city in the east. Zhangjiagang international port and State highway endow us a convenient water and land transportation which links us to the outside world both home and aboard. Chewit International is one group company with two manufactures one is producing steel forgings for Marine, Power, Boiler, Ocean, Oil, Petrochemical, Mechanical and Hydraulic fields and the other is producing precision steel tubes for automotive industry and hydraulic system and also one semi-independent company specially for import and export business. We have a total area of 150000 square meters with the employees over 200 people. All the products well produced by our mills need to be double inspected by chewit professional quality controller and then we will offer our customer the vivid report for the tested items. Only those products which are inspected well can be allowed to delivery to our customers. By the means of strict inspection, we wined a lot of customer for long term business both home and abroad. We have customers like Danieli, Cedervall,Wartsila,Sannat mansur, SeaLink, Tata Group, Continental, Iran Khodro and also other well reputated ones. We adhere to our company tenet Customer First, Quality formost and always try our best to serve our customer with our full heart.  Packaging & Shipping /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
