Even in the most demanding situations, our bolts, nuts, washers, and studs provide long-lasting performance since they are manufactured in accordance with DIN, ASTM B446, and ASME SB446 requirements.
Table Of Content
Inconel 625 is a nickel-based alloy containing chromium and molybdenum, known for its exceptional resistance to oxidation, pitting, and crevice corrosion. This property makes it ideal for use in acidic and high-salinity environments. With a tensile strength of at least 930 MPa and a yield strength of 517 MPa, it maintains its durability even at temperatures reaching 980°C. Inconel 625 is widely used in applications requiring strong mechanical properties and thermal stability. It is also recognized under equivalent standards such as UNS N06625 nuts and WNR 2.4856 bolts.
We offer Inconel 625 fasteners in various types, including hex bolts, socket head cap screws, studs, nuts, washers, and threaded rods, with sizes ranging from M3 to M56 and 3/6” to 2”. Available in both hot-forged and cold-drawn forms, our fasteners can be supplied with plain, passivated, or coated finishes based on project requirements. Additionally, we provide custom fabrication to ensure precise fitment for specialized applications.
Because of their high-temperature and corrosion resistance, Inconel 625 nuts and bolts are widely used in gas turbines, heat exchangers, nuclear reactors, exhaust manifolds, seawater processing systems, and chemical plants. Their ability to resist chloride-induced stress corrosion cracking makes them ideal for marine and offshore structures, where exposure to saltwater and extreme pressure is constant.
As a leading supplier and exporter of Inconel 625 fasteners, we are committed to providing premium-quality products, competitive pricing, and timely delivery worldwide. Whether you need bulk orders, specific dimensions, or customized solutions, we have the expertise and inventory to meet your needs.
