Al Summan Metals, a prominent manufacturer and supplier based in Dubai, UAE, has established a strong reputation for providing high-quality Stainless Steel 347 Bars/Rods. These bars are engineered to offer exceptional resistance to intergranular corrosion and high-temperature oxidation, making them ideal for demanding industrial environments. Al Summan Metals takes pride in precision engineering and stringent quality control to guarantee compliance with international standards, supplying Stainless Steel 347 Bars/Rods in a range of sizes and finishes. With a firm emphasis on durability, strength, and performance, the company serves industries such as chemical processing, power generation, and petrochemical manufacturing.
The composition of Stainless Steel 347 Bars/Rods consists of chromium (17–19%), nickel (9–13%), carbon (0.08% max), together with manganese, silicon, and niobium, which serves to stabilize the structure against carbide precipitation. This distinctive mixture provides them with outstanding resistance to corrosion and oxidation. The bars feature a tensile strength of roughly 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. They likewise retain excellent mechanical stability and creep strength under high temperatures, which makes them well suited for extended use in thermal and corrosive settings.

Stainless Steel 347 Bars and Rods deliver outstanding corrosion resistance, particularly in high-temperature settings. They offer superb oxidation resistance and are extremely resistant to intergranular corrosion, which makes them well-suited for sectors such as aerospace, chemical processing, and power generation.
These bars and rods work excellently in high-temperature settings, such as heat exchangers, furnace components, chemical reactors, and machinery across sectors like aerospace, chemical processing, and power generation, where withstanding oxidation and scaling is essential.
Stainless Steel 347 Bars/Rods are widely used across industries requiring both high-temperature strength and resistance to corrosion. They work exceptionally well for heat exchangers, furnace components, pressure vessels, boiler tubes, and exhaust systems. Because they are stabilized with niobium, these bars are particularly suitable for welded structures in chemical, petroleum, and food processing plants. On top of this, they serve in aircraft exhaust manifolds, power generation systems, and refineries. Their combination of durability, weldability, and resistance to intergranular attack ensures dependable performance in both oxidizing and moderately corrosive conditions.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
