Stainless Steel 316 / 316L Round Bar

ASTM A276 316 Stainless Steel Round Bar Stockist in Mumbai India. ASTM A276 316L Hex Bar, Flat Bar, Forged Bar, Square Bar SS 316 / 316L Bright Bar Stockist and Supplier in Mumbai India.


Stainless Steel 316 / 316L Round Bars are solid cylindrical metal rods known for their strong corrosion resistance, especially in chloride-rich environments. These bars are made from stainless steel grades 316 (1.4401) and 316L (1.4404), containing elements like chromium, nickel, molybdenum, manganese, and carbon. Grade 316L has lower carbon content, which improves its weldability and resistance to sensitization. At Preston Pipes & Alloys, we manufacture these round bars using rolled or forged methods. Our process ensures accurate dimensions, clean surface finishes, and reliable performance. As a trusted Stainless Steel 316L round bar suppliers, we follow industry-approved techniques and offer round bars that meet global standards.


These round bars offer good strength and durability. Grade 316L provides a minimum tensile strength of 485 MPa and a minimum yield strength of 170 MPa. It also offers excellent ductility and high-temperature performance. With a density of 8000 kg/m³ and thermal conductivity ranging from 16.3 to 21.5 W/m.K, they perform well in both mechanical and thermal conditions. These bars resist scaling and maintain their structure even under high heat. Our 316 stainless steel square bar is also available for specific industrial applications needing high reliability.
