Anucha Metals stands out as a top manufacturer and supplier of Stainless Steel 347H Hex Bars right in the heart of Bangkok, Thailand. We take pride in offering high-quality stainless steel products that are engineered for exceptional performance, especially in high-temperature and corrosive settings. Our 347H hex bars are celebrated for their remarkable resistance to intergranular corrosion, impressive creep strength, and overall durability, making them a perfect fit for industries like petrochemical, chemical, and power generation. Crafted with precision and a commitment to international standards, these bars guarantee dimensional accuracy, a long service life, and reliable performance. At Anucha Metals, we provide stainless steel solutions that are specifically designed to meet the critical demands of industries around the globe.
Our Stainless Steel 347H Hex Bars are made from a niobium-stabilized austenitic stainless steel alloy, featuring a higher carbon content than the standard 347, which enhances their high-temperature strength. They boast excellent mechanical properties, including outstanding tensile and yield strength, good toughness, and resistance to creep and stress rupture even at elevated temperatures. The addition of niobium improves resistance to carbide precipitation, ensuring stability during extended heat exposure. These bars effectively combine corrosion resistance with mechanical strength, making them ideal for high-temperature applications that require reliability.

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.
You’ll find Stainless Steel 347H Hex Bars widely utilized in industries that demand materials capable of withstanding both heat and corrosive environments. They are often used in chemical processing equipment, heat exchangers, boiler tubes, and furnace components due to their strong resistance to oxidation and intergranular corrosion. In the petrochemical and power generation fields, they serve critical roles in superheater tubes, turbine parts, and high-temperature piping systems. Additionally, the construction and engineering sectors rely on them for structural applications that face heat and stress. With their durability, strength, and corrosion resistance, 347H hex bars are the go-to choice for challenging industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
