One of their standout offerings, the Stainless Steel 347H Hex Bar, is celebrated for its exceptional heat resistance, corrosion protection, and structural reliability. Crafted using cutting-edge technology and rigorous quality controls, Rashid Metals guarantees that each hex bar adheres to international standards and meets specific customer requirements. With a strong emphasis on precision, durability, and timely delivery, the company has become a trusted partner for industries such as petrochemical, power generation, construction, and engineering, both in Oman and beyond, providing dependable and long-lasting stainless-steel solutions.
The Stainless Steel 347H Hex Bar is a high-carbon, niobium-stabilized austenitic stainless steel that includes chromium, nickel, and columbium (niobium), which effectively prevents intergranular corrosion. The higher carbon content boosts its strength at elevated temperatures, enhances creep resistance, and ensures mechanical stability. On the mechanical front, SS 347H boasts impressive tensile strength, good toughness, and reliable performance even under prolonged heat exposure. Its stabilization helps avoid carbide precipitation during welding or thermal cycling, preserving its structural integrity and oxidation resistance. These characteristics make it perfect for applications that demand durability, heat resistance, and consistent mechanical reliability in challenging industrial settings.

SS 347H stainless steel contains high carbon content (0.04–0.10%), along with chromium (17–19%) and nickel (9–12%), which enhance its resistance to high temperatures and intergranular corrosion. Its stabilizing addition of tantalum or niobium prevents carbide precipitation, making it ideal for high-stress applications like hexagonal bars.
The high carbon content in SS 347H enhances its high-temperature strength and resistance to creep, making it suitable for extreme heat environments. Unlike lower-carbon steels, it stabilizes its microstructure, preventing carbide precipitation and improving oxidation resistance, which is crucial for high-temperature applications compared to other stainless steels like 304 or 316.
SS 347H Hex Bar is commonly used in the aerospace, chemical processing, and power generation industries. It is preferred for its excellent high-temperature resistance, resistance to intergranular corrosion, and stability in harsh environments. Its ability to withstand extreme temperatures and prevent carbide precipitation makes it ideal for critical applications.
Stainless Steel 347H Hex Bar finds extensive use in industries that require high-temperature strength, corrosion resistance, and mechanical durability. It’s commonly utilized in heat exchangers, boiler components, furnace parts, and high-temperature piping systems. In sectors like petrochemical, oil and gas, and power generation, SS 347H hex bars are essential for flanges, fittings, manifolds, and structural supports that face continuous thermal stress. Their excellent weldability and oxidation resistance also make them a great fit for aerospace, chemical processing, and other demanding applications.
