Kanish Metals stands out as a reliable manufacturer and supplier of Stainless Steel 347H Hex Bars in Dubai, UAE. They offer top-notch products specifically designed to thrive in high-temperature and corrosive environments. This particular grade of stainless steel, 347H, is niobium-stabilized and has a higher carbon content than its counterpart, 347, which gives it exceptional creep and stress-rupture resistance when the heat is on. The hex bars crafted from this material are known for their durability, precision, and dependable performance, making them perfect for critical industrial applications. Thanks to their advanced manufacturing techniques, rigorous quality control, and prompt delivery, Kanish Metals has built a solid reputation as a trusted supplier of Stainless Steel 347H Hex Bars across various industries in the region.
These hex bars are made up of 17–19% chromium, 9–13% nickel, and niobium, which helps prevent carbide precipitation during high-temperature use. They boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. The increased carbon content not only enhances creep resistance but also ensures excellent mechanical stability and outstanding performance in high-temperature settings. With remarkable oxidation resistance and durability, these hex bars are well-suited for tough operating conditions where a long service life is crucial.

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 Bars find their place in industries that demand high-temperature strength, corrosion resistance, and dimensional stability. They are perfect for applications like boiler tubes, furnace components, heat exchangers, chemical processing equipment, pressure vessels, and petrochemical plants. Their ability to resist intergranular corrosion after welding makes them ideal for welded assemblies that face prolonged high-temperature service. Additionally, they are utilized in aerospace, power generation, and marine environments. With a reliable mix of strength, durability, and heat resistance, Stainless Steel 347H Hex Bars ensure optimal performance in essential engineering and industrial applications.
