Chuck Metals, based in Pulau Ujong, Singapore, is a reliable manufacturer and supplier of top-notch stainless steel products, including Stainless Steel 317 Hex Bars and Rods. These bars are crafted to endure harsh chemical environments and find their place in various industries like pharmaceuticals, marine, chemical processing, and pulp and paper. With a commitment to precision manufacturing and adherence to international standards, Chuck Metals has earned a reputation as a trusted partner for stainless steel across Singapore and Southeast Asia.
Stainless Steel 317 Hex Bar/Rod is a high-alloy austenitic stainless steel that contains 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and up to 0.08% carbon. This alloy is known for its impressive resistance to pitting and crevice corrosion, particularly in chloride and acidic environments. Its mechanical properties include a tensile strength of around 75 ksi (515 MPa), yield strength of about 30 ksi (205 MPa), and elongation of approximately 35–40%. The alloy maintains its strength and corrosion resistance even at elevated temperatures, along with excellent formability and weldability.

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.
Stainless Steel 317 Hex Bars and Rods are ideal for high-stress and corrosive applications, such as fasteners, valves, shafts, marine hardware, and chemical equipment. Their hexagonal shape makes them easy to grip during machining and assembly, which is perfect for precision components. Industries favor 317 for its durability, low maintenance needs, and outstanding resistance to harsh chemicals and saltwater. These bars deliver long-lasting performance in environments where both mechanical strength and corrosion protection are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
