Automotive Tube manufacturers ASTM A519 seamless tubing covers several grades of carbon and alloy steel seamless tubing. A519 4130 and 4140 tubing are two kinds of alloy steel which are commonly used as raw materials in the automotive industry. A519 4130 is a kind of low alloy steel which contains molybdenum and chromium as strengthening component. The carbon content of 4130 tubing is between 0.28% to 0.33%, as the carbon content is relatively low, 4130 steel tube is good for fusion weld. This material can be hardened by heat treatment. AISI 4140 tube is medium carbon alloy steel tube, which is widely used for general purpose applications that require high tensile strength and toughness. The addition of chromium and molybdenum, along with heat treatment contribute to the combined advantage of hardness, ductility, and strength. Typical application in the automotive industry for 4140 mechanical tubing is rotor shaft. Dingxin has been producing 4130 tubing and 4140 tubing for around 20 years and enjoy premium quality reputation from many international clients. 聽 Product Details 聽 Product nameASTM A519 SAE AISI 4130 4140 QT seamless tubing StandardASTM A519 MaterialSAE 4130 4140 DimensionOD: 16-245mm, WT1-32mm, Length: 3-6m Delivery conditionCold worked, Stress Relieved, Normalized, Annealed, Quenched and tempered CertificateISO 9001, IATF 16949 ApplicationsAutomotive parts PackagingLong pipe: hexagonal bundles with steel-hooped.
