SS 316 & 316L Round Bar Manufacturer

Precision Alloy is a trusted manufacturer and global supplier of SS 316 & 316L Stainless Steel Round Bars, engineered for maximum corrosion resistance, exceptional weldability, and outstanding performance in harsh environments. Designed for chemical processing, marine engineering, and high-salinity applications, these bars are available in multiple sizes and finishes.

We supply these austenitic grades with precise tolerances and surface finishes, strictly adhering to international standards such as ASTM A276, ASME SA479, EN 10088, and DIN 1.4401 / 1.4404.

What Are SS 316 & 316L Round Bars?

SS 316 contains molybdenum (2–3%) to enhance its resistance to pitting and crevice corrosion in chloride-rich environments. SS 316L, the low-carbon version, improves weldability and reduces the risk of intergranular corrosion post-welding. These bars are ideal for high-temperature, marine, and corrosive service environments.
