Ojas Pipes and Tubes, a company headquartered in Kolkata, India, is a reliable manufacturer and supplier of high-strength Stainless Steel 316 and 316L EFW (Electric Fusion Welded) Pipes. With a reputation for high-precision engineering and excellent strength, Ojas maintains the highest level of quality control to ensure that all pipes adhere to high industry standards of performance and reliability. Equipped with sophisticated manufacturing processes and a reliable supply chain, the company supplies varied industrial requirements domestically and abroad. Their Stainless Steel 316 and 316L EFW Pipes are well renowned for high corrosion resistance, good weldability, and extended service life, which has made Ojas Pipes and Tubes a popular choice in numerous industries.
Stainless Steel 316 and 316L EFW Pipes consist mainly of iron, with 16-18% chromium, 10-14% nickel, and 2-3% molybdenum for higher corrosion resistance and strength. The “L” type contains less carbon (less than 0.03%), better weldability, and lower carbide precipitation. Mechanically, they provide superior tensile strength of approximately 515 MPa, yield strength of around 205 MPa, and elongation of close to 40%, offering good ductility as well as toughness. Their high resistance to chloride-induced pitting and crevice corrosion makes them suitable for hostile environments, ensuring reliability and durability in critical use.

Stainless Steel 316 and 316L EFW Pipes are used heavily in the chemical process, pharmaceutical, food process industries, marine, and petrochemical sectors for their excellent corrosion properties and toughness. Their high-temperature resistance and tolerance of aggressive chemicals also make them suitable for conveying fluids and gases under corrosive environments. Moreover, pipes are also used in power plants, desalination, and sewage treatment plants. The 316L grade is used where the above higher weldability and intergranular corrosion resistance are needed, for instance, in surgical hardware and in architecture, for structural integrity and longevity.
