Chung Metal provides Stainless Steel 317 Hex Bars and Rods, a high-performance stainless steel for extreme environments with severe chloride or chemical exposure. Produced in Da Nang, Vietnam, this high-molybdenum, high-nickel alloy provides enhanced corrosion resistance and strength over traditional 316 grades. Chung Metal supplies 317 hex bars in a variety of sizes and finishes, well-suited for pressure systems, chemical plants, and marine engineering.
317 has 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and carbon ≤ 0.08%. It provides tensile strength of up to 700 MPa, yield strength ~205–275 MPa, and elongation ~35–40%. It is not magnetic and maintains very good strength and corrosion resistance even under thermal and chemical stress.

SS 317 hex bars/rods are commonly used in the industrial and construction sectors for their corrosion resistance and high strength. They are utilized in manufacturing chemical processing equipment, marine environments, heat exchangers, pumps, valves, fasteners, and structural components in corrosive conditions, ensuring durability and reliability.
SS 317 hex bars/rods typically range from 6 mm to 100 mm in size, with tolerances as per ASTM A276 or similar standards. Precise dimensions and tight tolerances ensure consistent strength, machinability, and fitment, making them ideal for high-performance applications in chemical, marine, and structural industries.
SS 317's chemical composition, with high levels of chromium (24-26%) and molybdenum (3-4%), enhances its resistance to pitting and crevice corrosion. The molybdenum content improves resistance to chloride-induced corrosion, while the balanced alloying helps prevent stress corrosion cracking, making it ideal for harsh, chloride-rich environments.
317 hex bars are suited for chemical processing equipment, marine fasteners, and corrosive environment structural components. It’s employed in acid-handling systems, dye-making, pollution control equipment, and high-chloride piping systems. 317 is utilized where improved corrosion protection and greater mechanical strength are required over the long term.
