Stainless Steel 316 Welded Tubes Manufacturer in India
What Are Stainless Steel 316 Welded Tubes?
Stainless Steel 316 Welded Tubes are austenitic stainless steel tubes containing chromium, nickel and molybdenum, providing excellent corrosion resistance in demanding environments. Grade 316, identified by UNS S31600, is widely selected where resistance to chlorides, chemicals and general corrosion is required.
The addition of molybdenum gives Stainless Steel 316 improved resistance to pitting and crevice corrosion compared with conventional chromium-nickel stainless steel grades. These characteristics make 316 welded tubes suitable for equipment exposed to marine atmospheres, chemical solutions and process fluids.
Stainless Steel 316 Welded Tubes can be supplied according to applicable ASTM and ASME specifications, including ASTM A249 and ASTM A312 where applicable to the product form and service requirements. Tube dimensions, wall thickness, heat treatment and testing can be selected according to the intended application.
These tubes are used in chemical processing equipment, marine systems, pharmaceutical equipment, food processing machinery, heat exchangers, petrochemical plants and water treatment systems. They are available in different sizes, wall thicknesses, lengths and finishes according to project requirements.
Kamal Steels is a reliable Stainless Steel 316 Welded Tubes Manufacturer and Stockist in India, supplying tubes in different sizes, wall thicknesses, lengths and finishes. We also cater to domestic and international requirements with suitable MTC, inspection documentation and export packaging.
