Isis Metals is a reliable manufacturer and supplier of Stainless Steel 347H Hex Bars, proudly based in Manila, Philippines. We’re known for providing top-notch stainless steel products that adhere to international standards. Our Stainless Steel 347H Hex Bars are crafted for outstanding performance in high-temperature and corrosive settings. Using only premium-grade raw materials and cutting-edge production techniques, these bars deliver remarkable strength, durability, and weldability. At Isis Metals, we guarantee precision-engineered Stainless Steel 347H Hex Bars that ensure long-lasting reliability and dimensional accuracy, making them perfect for industrial, chemical, and mechanical applications where strength and heat resistance are crucial.
Stainless Steel 347H Hex Bars are a type of stabilized austenitic stainless steel, made up of chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), manganese (2% max), silicon (1% max), and niobium (10×C–1%) to prevent carbide precipitation. These bars boast a tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. They excel in oxidation, creep, and corrosion resistance, even at high temperatures. Stainless Steel 347H Hex Bars maintain their mechanical strength and stability under thermal stress, making them ideal for demanding heat-intensive and high-pressure industrial applications.

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 extensive use in industries that demand exceptional heat resistance, mechanical strength, and corrosion protection. They’re perfect for applications like boiler tubes, heat exchangers, pressure vessels, furnace components, and exhaust systems. Their stability and creep resistance make them a great fit for chemical processing, power generation, petrochemical, and refinery operations. Additionally, these hex bars are utilized in aerospace, marine, and food processing sectors due to their durability and ease of fabrication. The outstanding weldability and toughness of Stainless Steel 347H Hex Bars further enhance their versatility across various applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
