Vinit Stainless, a well-known Chennai-based manufacturer and supplier, provides high-quality SS 301 tubing characterized by strength, formability, and resistance to corrosion. SS 301 is an austenitic stainless steel with good cold-working properties, and hence can be applied in structural and mechanical purposes of high-strength tubing. Vinit Stainless provides SS 301 tubes both in the welded and seamless condition, as per international standards like ASTM A213 and A269. Focusing on quality, accuracy, and timely delivery, Vinit Stainless provides dependable SS 301 tubing solutions to diverse industries such as automotive, aerospace, railways, and industrial fabrication.
SS 301 tubing contains 16–18% chromium, 6–8% nickel, ≤0.15% carbon, and traces of manganese and silicon. It offers superior mechanical strength, particularly after cold working. Tensile strength is between 520 MPa (annealed) and 930 MPa (full hard), and yield strength increases dramatically after tempering. SS 301 has good corrosion resistance in mildly corrosive conditions and has excellent ductility and toughness. It becomes stronger and more magnetic with cold working. These mechanical properties make SS 301 a good choice for precision tubing applications where strength and light weight are desired.

SS 301 tubing has extensive application in products that demand superior strength-to-weight ratio and good formability. Typical applications are railway coaches, architectural components, automotive trim, aerospace parts, and exhaust systems. The material finds application in appliances, conveyor systems, and mechanical assemblies as well. The material is especially recommended for roll-formed or stamped pieces and precision tubing that faces dynamic stress. Its moderate resistance to corrosion makes it suitable for use in indoor or mildly corrosive conditions. SS 301 tubing provides a blend of strength, ductility, and low cost, which makes it a material of choice for structural as well as for fluid transport systems in non-critical applications.
