Shriram Metal is an internationally recognized manufacturer and seller of Stainless Steel 316/316L Buttweld Fittings, providing high-quality solutions for a wide range of industrial applications. The austenitic stainless steel family includes SS 316 and SS 316L, which are noted for their exceptional corrosion resistance, strength, and weldability. The main distinction between the two grades is their carbon content—SS 316 has a higher carbon percentage, which increases its strength at high temperatures, whereas SS 316L (Low Carbon) is preferred for applications that require improved weldability and resistance to intergranular corrosion. These grades are commonly used in sectors such as chemical processing, pharmaceuticals, food processing, maritime engineering, power generation, and oil and gas, where excellent resistance to oxidation and pitting corrosion is required.
Shriram Metal manufactures SS 316/316L Buttweld Fittings of various kinds, including elbows, tees, reducers, crosses, caps, stub ends, and pipe bends, to ensure compatibility with diverse piping systems. Our fittings are intended to satisfy ASTM A403 requirements and go through rigorous quality inspections to ensure durability and dependability in harsh conditions. SS 316 and 316L are highly resistant to chloride-induced corrosion, making them appropriate for maritime applications and settings exposed to severe chemicals. Whether you want seamless or welded buttweld fittings, we offer personalized solutions to your individual project needs. For high-quality stainless steel buttweld fittings at low pricing, contact Shriram Metal at sales@shrirammetal.com now.
