We provide a wide range of stainless steel solutions designed for demanding industrial environments, all while maintaining a strong commitment to quality, innovation, and customer satisfaction. Stainless Steel 347H Stud Bolts are one of our most reliable products because of their remarkable strength, resistance to corrosion, and ability to withstand high temperatures. These fasteners are built for performance and dependability, making them perfect for use in industries like petrochemical, chemical processing, power generation, and marine. Vinit Stainless provides excellent and reasonably priced precision-engineered products to satisfy a wide range of customer needs.
The stabilized austenitic stainless steel alloy known as Stainless Steel 347H Stud Bolts is mainly made up of 17–19% chromium and 9–13% nickel, with niobium and tantalum added to improve performance at high temperatures and resistance to intergranular corrosion. The alloy has outstanding creep strength, oxidation resistance, and high tensile strength (up to 860 MPa). It also keeps its ductility and weldability high. Because of these characteristics, SS 347H Stud Bolts are ideal for structural elements subjected to high temperatures, harsh conditions, and continuous operation.
