Harsh Metalloys stands out as a leading manufacturer and supplier of Stainless Steel 301L Tubing, proudly based in Mumbai, India. This low-carbon, austenitic stainless steel, known as SS 301L, is celebrated for its remarkable strength, corrosion resistance, and formability, particularly when cold-worked. Our SS 301L tubes are crafted in line with international standards like ASTM A213 and ASTM A269, and they come in both welded and seamless options. These tubes find their place in various applications, including automotive parts, aerospace structures, railway cars, and architectural frameworks, where a high strength-to-weight ratio and exceptional resistance to wear and corrosion are essential.
Stainless Steel 301L Tubing is composed of 16–18% chromium, 6–8% nickel, and a low carbon content (≤0.03%), which boosts its weldability and corrosion resistance compared to standard 301. It boasts a tensile strength of up to 750 MPa, a yield strength of around 310 MPa, and an elongation of about 40%. SS 301L excels in resisting oxidation, atmospheric corrosion, and mechanical wear. While it is non-magnetic in its annealed state, it becomes strongly magnetic when cold worked. Its low carbon content also helps to prevent carbide precipitation during welding, making it a fantastic choice for fabrication and forming applications.
