316LN Pipes, Stainless Steel Pipes, Nitrogen-Enhanced Steel Pipes, EFW Steel Pipes, High-Pressure Steel Pipes
Kwality Steelage Pvt. Ltd., a trusted manufacturer, supplier, and exporter based in Mumbai, India, is proud to present A358 GR 316LN Stainless Steel Pipes. These pipes, engineered for critical applications, adhere to the ASTM A358 standard and are manufactured using the electric fusion welding (EFW) process. Known for their low carbon content and nitrogen enhancement, A358 GR 316LN pipes deliver exceptional strength, corrosion resistance, and performance in extreme environments. They are widely used in industries such as chemical processing, nuclear power generation, and marine engineering.
The A358 GR 316LN pipes come in nominal bore (NB) sizes ranging from 6 inches to 60 inches, with schedules including SCH 10, SCH 40, SCH 80, and SCH XXS, ensuring suitability for diverse industrial requirements. These pipes boast a robust composition of 16-18% chromium, 10-14% nickel, 2-3% molybdenum, and an addition of nitrogen (0.08-0.20%), which enhances pitting and crevice corrosion resistance. With low carbon content (<0.03%), these pipes offer excellent weldability and minimize the risk of intergranular corrosion during welding and heat treatment.
Manufactured under stringent quality controls, A358 GR 316LN Stainless Steel Pipes are precision-engineered with dimensional tolerances of ±1% for outside diameter and +12.5%/-10% for wall thickness. Available in various finishes such as polished, pickled, and passivated, they meet the demanding requirements of high-pressure and high-temperature systems. These pipes deliver superior mechanical properties, including a tensile strength of 515 MPa and a yield strength of 205 MPa, making them ideal for both structural and fluid transport applications.
Each pipe undergoes rigorous testing, including ultrasonic, radiographic, and hydrostatic examinations, to ensure compliance with international standards. Kwality Steelage Pvt. Ltd. also provides tailored solutions with custom lengths of up to 12 meters and end types such as plain, beveled, or threaded. Backed by global certifications and a commitment to quality, we cater to a diverse clientele across Europe, the Middle East, and Southeast Asia.

A358 GR 316LN Stainless Steel Pipes are heat-treated to optimize their mechanical properties and corrosion resistance. Processes include annealing and normalization, followed by pickling or passivation to ensure a clean, corrosion-resistant surface. Their nitrogen-enhanced composition offers improved strength and resistance to pitting and crevice corrosion. Weldability is excellent, with post-weld heat treatment (PWHT) recommended for critical applications.
