Stainless Steel 347H Stud Bolts consist of mostly iron, 17–19% chromium, 9–13% nickel, and columbium (niobium), with small amounts of carbon, manganese, and silicon. Niobium stabilization improves intergranular corrosion resistance, even at high temperatures of 900°C. These bolts possess high tensile strength, good creep resistance, thermal stability, and mechanical toughness in extreme environments. Their structure has good resistance to sensitization, with good weldability and high-heat applications. All these mechanical and corrosion-resistant qualities make 347H stud bolts perfect for long-term application in extreme industrial environments.
347H Stainless Steel Stud Bolts are critical in high-temperature, high-corrosion applications in various industries. In chemical plant facilities, they bolt-up systems that are subjected to corrosive acids and high temperatures. In the aerospace industry, they bolt down critical parts that are under thermal expansion and stress. Their ability to withstand sulfide stress corrosion cracking makes them critical in the oil and gas industry, especially in refineries. They are also commonly used in nuclear reactors due to their radiation and thermal cycling resistance. Being strong, durable, and resistant to corrosion, these bolts provide reliable fastening solutions in critical, high-risk applications.
