Aditya Stainless, a prominent manufacturer and supplier located in Kolkata, India, specializes in top-notch Stainless Steel 316H Tubing, celebrated for its remarkable high-temperature strength and outstanding corrosion resistance. SS 316H is a high-carbon variant of 316 stainless steel, crafted specifically for high-temperature applications where enhanced tensile and creep strength are crucial. Produced in accordance with international standards like ASTM A213/A269, this tubing is widely utilized in sectors that demand durability, thermal stability, and dependable performance. With precise dimensional tolerances and excellent weldability, Aditya Stainless guarantees that their SS 316H tubing meets the rigorous needs of the chemical, refining, and power generation industries.
Stainless Steel 316H Tubing is composed of 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and a higher carbon content (0.04–0.10%) compared to standard 316. This additional carbon boosts high-temperature tensile and creep strength, making it perfect for elevated service conditions. It boasts a minimum tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 30–35%. The tubing is resistant to pitting, crevice corrosion, and oxidation in chloride and acidic environments, while also maintaining excellent mechanical performance under extended thermal exposure.
