SS 316 Buttweld Fittings are tough to use in excessive stress systems. It gives fine weldability and protects from any leakage in the system. Our fittings are sustained in high thermal applications and prevent heat corrosion. These fittings are necessarily fine surface appearance to avoid rust while inside plane surface avoids corrosion due to reducing media.

SS 316/316L is composed of significant chromium and nickel value with the addition of molybdenum and other elements. Less carbon modifies to SS 316L that is more resistant to corrosion, while other characteristics are the same in both grades. SS 316L Buttweld Fittings provides better corrosion resistance due to less carbon value and is predominantly preferred in high-temperature systems. These fittings offer high strength and durability along with excellent weldability.
