316 / 316L

Overview and Applications

316 / 316L Stainless Steel Hex Bar is a molybdenum-bearing austenitic stainless steel product engineered for corrosion-resistant industrial and marine applications. Manufactured to ASTM A276 and ASTM A479 standards, it delivers high tensile strength, precise dimensional tolerances, and excellent machinability for CNC machining and structural fabrication. Its enhanced chromium, nickel, and molybdenum composition provides superior resistance to pitting, crevice corrosion, and chloride exposure, while the low-carbon 316L grade improves weldability and long-term performance in aggressive environments.

316 stainless steel hex bar is commonly used for shafts, fasteners, valves, fittings, marine hardware, and custom-machined components in offshore oil & gas, chemical processing, marine construction, food processing, and heavy industrial applications where durability and maximum corrosion resistance are critical.

Performance & Material Advantages

316 / 316L stainless steel hex bar offers an advanced combination of corrosion resistance, mechanical strength, and fabrication efficiency for critical industrial applications. Its molybdenum-enhanced chemical composition significantly improves resistance to chloride-induced corrosion, pitting, and stress corrosion cracking compared to standard 304 grades. The low-carbon 316L variant enhances weldability and reduces carbide precipitation, making it highly suitable for welded assemblies, pressure systems, marine components, and high-performance engineered structures operating in corrosive and high-moisture environments.

Technical Specifications

316 / 316L Stainless Steel Hex Bar is manufactured in compliance with ASTM A276 and ASTM A479 standards, ensuring controlled chemical composition and consistent mechanical properties. Containing 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, this marine-grade stainless steel hex bar provides excellent corrosion resistance, including superior protection against pitting and chloride exposure. Available in cold-finished and annealed conditions, it offers tight dimensional tolerances, smooth surface finish, and reliable machinability for CNC machining, marine components, chemical processing equipment, and corrosion-resistant structural applications.
