Al Summan Metalsis a manufacturer, distributor and supplier of SS 347 Hex Bars and rods, providing corrosion resistance on par with SS 302 Hex Bars Our stainless steel 347 hex bars are built from columbium-strength austenitic steel free of hard materials, comparing favorably to stainless steel 321 hex bars Effective in oxidizing settings for general corrosion resistance and strong performance. The stainless steel 347H hex bars are exceptionally durable with columbium and tantalum to prevent chromium carbide formation. This stabilizer boosts their corrosion resistance in severe oxidizing conditions, making them a dependable option for demanding applications. SS 347 Hex Bars and rods deliver excellent resistance to intergranular corrosion, even following exposure to the temperature of chromium carbide precipitation within the range of 800°F to 1500°F (427°C to 816°C).
SS 347 Hex Bars/Rodscontain chromium (17-19%), nickel (9-13%), columbium, tantalum (stabilizer), along with manganese, silicon and carbon in regulated proportions They possess a very low tensile strength of 515 MPa and a minimum yield strength of 205 MPa is supplied, with a length of 40% at 50mm and there is a . These rods deliver outstanding stability, even under cryogenic temperatures, and superb resistance to oxidation and inter-granular corrosion. Their stability guarantees durability in high-temperature settings, rendering them perfect for the chemical, gas, aerospace and electrical industries.

SS 347 Hex Bars find broad use in aerospace, chemical processing, and power generation for applications demanding high-temperature resistance, corrosion resistance, and strength. They surpass other grades thanks to their niobium stabilization, which prevents carbide precipitation and guarantees durability.
SS 347 Hex Bars generally display a tensile strength ranging from 515-750 MPa, a yield strength of 205 MPa, and a minimum elongation of 40%. These characteristics guarantee excellent durability, flexibility, and performance across challenging applications.
SS 347 Hex Bars typically conform to standards such as ASTM A276, ASTM A479, ASME SA479, and AMS 5646. These certifications guarantee quality, dimensional accuracy, and performance for high-temperature and corrosion-resistant applications across industries, satisfying rigorous safety and reliability requirements.
SS 347 hex barsare extensively used across industries that demand exceptional corrosion resistance and strength at elevated temperatures. Their main applications cover chemical and petrochemical processing, where they effectively manage acetic, sulfuric, and phosphoric acids. Because they resist intergranular corrosion, they are indispensable in heat exchangers, pressure vessels, and boiler components. Within the aerospace and automotive industries, these bars serve in engine parts and exhaust systems. Furthermore, they find use in food processing, pharmaceutical equipment, and power generation owing to their durability and weldability.
We supply products that include mill test certificates as well as third-party test certificates, guaranteeing the highest standards of quality and compliance.
