Harsh Metalloys, based in Mumbai, India, stands out as a leading manufacturer and supplier of top-notch Stainless Steel Mechanical Tubing, crafted for tough structural and mechanical uses. We use only the finest stainless steel grades like 304, 316, 310, 321, and 904L, ensuring our tubing boasts remarkable strength, resistance to corrosion, and precise dimensions. Our tubes come in both welded and seamless options, available in various diameters, wall thicknesses, and surface finishes. At Harsh Metalloys, we provide mechanical tubing that meets international standards such as ASTM A511 and A554, catering to industries like automotive, aerospace, construction, and industrial machinery.
Stainless Steel Mechanical Tubing is generally made up of 18–25% Chromium and 8–22% Nickel, with optional elements like Molybdenum found in grades such as 316 or 904L to enhance corrosion resistance. This mechanical tubing delivers tensile strength ranging from 485–750 MPa and yield strength between 170–550 MPa, depending on the grade and whether it’s annealed or cold-worked. These tubes are celebrated for their impressive strength-to-weight ratio, outstanding fatigue resistance, and good weldability. Our precision manufacturing guarantees tight tolerances, smooth surfaces, and dependable performance in load-bearing and high-pressure situations.
