Mumbai, India-based The Fasteners Mart is a leading producer and supplier of high-quality fasteners to meet various industrial requirements. With expertise in long-lasting and corrosion-resistant solutions, they provide Stainless Steel 347H Stud Bolts that are designed for high-temperature use. With their exceptional strength and outstanding resistance to oxidation, these stud bolts ensure sound performance in harsh environments, and hence are perfect for critical applications in different industries.
Stainless Steel 347H Stud Bolts are manufactured from an iron alloyed with chromium (up to 18-20%), nickel (9-13%) and tantalum, with a slight addition of niobium to improve high-temperature resistance. This grade has exceptional corrosion resistance, particularly in sulfuric acid and other aggressive media. Mechanically, 347H stud bolts provide high tensile strength (up to 520 MPa), superior oxidation resistance, and excellent creep and stress rupture characteristics, which make them suitable for applications at high temperatures like power plants and chemical processes.

Stainless Steel 347H Stud Bolts find extensive application in corrosive and high-temperature environments because of their superior scaling and oxidation resistance. Typical applications are in power plants, chemical processing and petrochemical industries, where they are employed in reactors, pressure vessels, and heat exchangers. These stud bolts are also well suited for furnace components, gas turbines, and steam boilers. Due to their capacity to endure harsh conditions, these materials are a good option for industries that need high-performance and durable fastening solutions.
At The Fasteners Mart, our stainless steel 347H stud bolts are tested thoroughly for quality to provide optimum performance and strength. Every bolt is put through strict processes such as hardness tests, chemical testing by spectroanalysis and Positive Material Identification (PMI) tests. Tensile strength tests, micro- and macrostructure analysis, and high thermal resistance tests are also performed on the material to ensure material integrity under harsh conditions. Specifically engineered to deliver high standards of corrosion resistance and long-term durability, our stud bolts are well-packed for secure transportation and dispatched in a state ready for direct use in applications where reliability counts—providing peace of mind and reliable performance every time.
