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.
Neith Metals’ Stainless Steel 347H Hex Bars are extensively utilized in sectors that demand high-temperature strength and corrosion resistance. They are particularly well-suited for creating heat exchangers, boiler tubes, furnace components, chemical processing equipment, and exhaust systems. Additionally, these bars find applications in aerospace, petrochemical, and power generation machinery, where dimensional stability, long-lasting durability, and resistance to thermal fatigue are essential. The hexagonal shape of these bars facilitates easy machining, assembly, and structural integration, making them a reliable choice for high-performance solutions in industrial and engineering applications facing extreme conditions.
