Neeka Tubes is a leading supplier of Stainless Steel (SS) 316L Round Bars. This is an austenitic chromium-nickel-molybdenum alloy that is a low-carbon variant of the standard 316 grade. It is recognized for being very strong, resistant to corrosion and durable, which makes it a perfect choice for demanding environments. You can get them in different shapes, like hexagonal, square, round, forged, bright, black, and cold drawn.
The specific chemical composition of SS 316L Round Bar provides superior performance.Β Nickel (10β14%) provides strength, toughness and excellent corrosion resistance. Chromium (16β18%) ensures that it lasts longer and doesn’t rust as easily. Molybdenum (2β3%) also makes it even more resistant to corrosion, especially pitting and crevice corrosion.
It has a tensile strength of 75 ksi, yield strength of 30 ksi and 40% elongation. This provides excellent strength and flexibility. It has a hardness of 217 Brinell and 95 Rockwell B. This makes it perfect for use in chemical, industry and marine settings. All of these qualities work together to make the material very strong and flexible making it a good choice for use in high-stress applications.

Due to its excellent corrosion resistance and high mechanical strength, Stainless Steel 316L Round Bar is a crucial material in demanding applications. Key industries that utilize it include the marine sector for saltwater exposed equipment, the chemical and food processing industries for hygiene and media resistance, and the pharmaceutical and aerospace fields for high-specification components. It is commonly used to produce items such as shafts, fasteners, and heat exchangers. To get the latest SS 316L Round Bar price and availability, please contact us directly.
