Mourad Metals stands out as a trusted manufacturer and supplier of Stainless Steel 347H Hex Bars, proudly based in Tunis, Tunisia. They cater to a diverse array of industrial sectors around the globe. Known for their cutting-edge manufacturing techniques, rigorous quality control, and a strong focus on customer satisfaction, Mourad Metals delivers Stainless Steel 347H Hex Bars that are specifically engineered for high-temperature and high-stress environments, ensuring exceptional durability and reliability. With a commitment to precision, timely deliveries, and adherence to international standards, they offer stainless steel solutions that are customized to fit the unique needs of various projects and industries.
The Stainless Steel 347H Hex Bar is an austenitic chromium-nickel alloy that’s been stabilized with niobium, which helps it resist carbide precipitation when exposed to high temperatures. Typically, it contains 17–19% chromium, 9–13% nickel, and a carefully controlled carbon content that boosts its creep strength. This material is known for its impressive tensile and yield strength, remarkable toughness, and excellent resistance to intergranular corrosion. It also retains oxidation resistance and mechanical stability even at elevated temperatures, along with good weldability and formability.

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.
These Stainless Steel 347H Hex Bars are extensively used in situations that require dependable performance in high-temperature and corrosive settings. You’ll often find them in petrochemical plants, oil and gas refineries, power generation facilities, and chemical processing equipment. Common applications include heat exchangers, boilers, pressure vessels, furnace components, and high-temperature fasteners. The hexagonal shape is perfect for machined parts, fittings, and structural elements, ensuring a long service life even in the toughest industrial conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
