Top manufacturer and supplier of 316L stainless steel bars in China. Offering corrosion-resistant round bars with superior formability, strength, and weldability for industrial applications.
316L stainless steel bar is a low-carbon, molybdenum-bearing austenitic stainless steel with superior corrosion resistance, especially in chloride-rich and acidic environments. Compared to standard 304 or 302 stainless steel bars, 316L exhibits enhanced pitting and crevice corrosion resistance, making it a preferred choice in marine, chemical processing, food equipment, and pharmaceutical sectors.
Our factory specializes in precision manufacturing and custom dimensions, ensuring strict tolerance control, smooth surface finish, and compliance with global industrial standards. As a trusted custom stainless steel bar manufacturer and supplier in China, we support OEM/ODM requests, full certification, and worldwide logistics.

316L stainless steel bars are most commonly produced in round bar form, ranging from small-diameter precision rods to large-diameter structural bars. These can be supplied in hot rolled, cold drawn, or centerless ground finishes. While round bars dominate, we also support custom machining into square, hexagonal, or flat profiles based on your project requirements. All bars are available in bright, pickled, or polished surfaces, tailored to functional or aesthetic applications.
