Stainless Steel 316H Welded Tubes Manufacturer in India
What Are Stainless Steel 316H Welded Tubes?
Stainless Steel 316H Welded Tubes are high-carbon austenitic stainless steel tubes containing chromium, nickel and molybdenum. Grade 316H, identified by UNS S31609, is developed for applications where elevated-temperature strength and corrosion resistance are required.
The higher carbon content of 316H helps provide increased strength at elevated temperatures compared with the standard 316 grade. Its molybdenum addition also improves resistance to pitting and crevice corrosion, making the material suitable for demanding process and high-temperature environments.
Stainless Steel 316H Welded Tubes can be supplied according to applicable ASTM and ASME specifications, including ASTM A249 and other applicable specifications depending on the product form, dimensions and service requirements. Tubes can be supplied in different outside diameters, wall thicknesses, lengths and finishes.
These tubes are used in chemical processing equipment, heat exchangers, petrochemical systems, power generation equipment, process plants and high-temperature industrial applications. The combination of molybdenum-enhanced corrosion resistance and elevated-temperature strength makes 316H suitable for demanding service conditions.
Kamal Steels is a reliable Stainless Steel 316H Welded Tubes Manufacturer and Stockist in India, supplying tubes in different sizes, wall thicknesses, lengths and finishes. We cater to domestic and international requirements with suitable MTC, inspection documentation and export packaging.
