Stainless Steel 347H Pipes are primarily made up of chromium (17–19%) and nickel (9–13%), with niobium added to enhance resistance to intergranular corrosion. The higher carbon content improves high-temperature strength and creep resistance, making this grade ideal for continuous heat exposure. On a mechanical level, 347H delivers excellent tensile and yield strength, good ductility, and reliable stability under thermal stress. Its ability to maintain structural integrity in fluctuating temperature conditions makes it perfect for applications that demand long-lasting durability and oxidation resistance.
