Fajar Metals, a leading manufacturer and supplier located in Jakarta, Indonesia, specializes in precision-engineered Incoloy 825 Stud Bolts that are perfect for tough industrial applications. Crafted from a corrosion-resistant nickel-iron-chromium alloy, these bolts also include molybdenum, copper, and titanium, which together ensure exceptional durability in both oxidizing and reducing environments. Built to meet international standards like ASTM B425 and ASTM B564, Incoloy 825 stud bolts provide impressive mechanical strength and corrosion resistance. They’re ideal for use in chemical processing, marine engineering, oil & gas operations, and pollution control systems, where dependable fastening solutions are essential for lasting performance.
Incoloy 825 Stud Bolts are made up of Nickel (38–46%), Iron (the balance), Chromium (19.5–23.5%), Molybdenum (2.5–3.5%), Copper (1.5–3%), and Titanium (0.6–1.2%). This unique blend offers remarkable resistance to acids like sulfuric and phosphoric acid, as well as protection against intergranular and pitting corrosion. These bolts boast a tensile strength of about 585 MPa, a yield strength of 220 MPa, and an elongation of around 30%. Their robust mechanical properties and corrosion resistance make them ideal for high-pressure, high-temperature, and chemically aggressive environments.
