Welcome to Nimish Metal, your trusted partner in Safat, Kuwait, for premium stainless steel solutions. We take pride in supplying high-performance materials, including our reliable Stainless Steel 347H Hex Bar. Engineered for demanding environments, this specific grade is an excellent choice for projects where strength and resistance to corrosion are paramount, offering exceptional value and longevity for our clients throughout the region.
The composition of Stainless Steel 347H is stabilized with columbium, which gives it superior resistance to intergranular corrosion following exposure to high temperatures. This stabilization also contributes to its impressive mechanical properties, including enhanced creep strength and excellent durability under stress, making it a robust material capable of performing reliably in challenging conditions.

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 the Stainless Steel 347H Hex Bar at work in some of the most critical applications. It’s a go-to material for components in the aerospace, chemical processing, and power generation industries, particularly for parts like valves, fasteners, and pump shafts that operate in high-temperature settings. Its ability to maintain integrity under thermal stress makes it indispensable for equipment that demands unwavering performance and safety over its entire lifespan.
