Inconel 625 fasteners are primarily made up of nickel (at least 58%), chromium (20–23%), and molybdenum (8–10%), along with trace amounts of iron, niobium, and other elements. This unique blend provides the fasteners with exceptional resistance to oxidation and corrosion, even in the harshest environments, such as acidic and saline conditions. On the mechanical side, they boast high tensile strength, excellent creep resistance, and reliable performance at temperatures soaring up to 980°C. The material retains its toughness and ductility across a broad temperature spectrum, making it perfect for applications that demand both mechanical strength and long-lasting reliability under severe thermal and chemical stress.
