Harsh Metalloys, a reputable manufacturer and supplier based in Mumbai, India, specializes in high-quality Stainless Steel 317 Tubing, renowned for its outstanding corrosion resistance and mechanical strength. SS 317 is a molybdenum-bearing austenitic stainless steel designed to withstand chemical attacks, especially in acidic and chloride-heavy environments. Our tubing comes in both seamless and welded options, adhering to ASTM A269, A213, and A249 standards. It’s commonly utilized in sectors like chemical processing, pharmaceuticals, pulp & paper, and marine applications. SS 317 tubing excels in high-temperature, corrosive, and high-pressure conditions.
Stainless Steel 317 Tubing is composed of 18–20% Chromium, 11–15% Nickel, and 3–4% Molybdenum, with a low carbon content that boosts its corrosion resistance. These tubes deliver tensile strength ranging from 515–750 MPa and a yield strength of about 205 MPa. The inclusion of molybdenum enhances resistance to pitting, crevice corrosion, and overall chemical degradation. SS 317 retains impressive mechanical properties up to 870°C (1600°F) and is non-magnetic when annealed. It also offers good weldability and formability, making it perfect for applications that demand high resistance to both oxidizing and reducing environments.
