Fajar Metals, a well-respected manufacturer and supplier based in Jakarta, Indonesia, specializes in top-quality Incoloy 825 Bolts that are renowned for their exceptional corrosion resistance and impressive mechanical strength. These bolts are made from a nickel-iron-chromium alloy, further enhanced with molybdenum, copper, and titanium, making them perfect for challenging chemical and marine environments. Manufactured to meet standards like ASTM B425 and ASTM B564, Incoloy 825 bolts find extensive use in chemical processing, offshore platforms, and acid-handling systems. Their remarkable durability and performance under high stress and corrosive conditions make them vital for critical industrial fastening needs.
Incoloy 825 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 chemical composition provides excellent resistance to both oxidizing and reducing acids, such as sulfuric and phosphoric acids. These bolts boast a tensile strength of 585 MPa, a yield strength of 220 MPa, and an elongation of about 30%. Their mechanical stability and corrosion resistance guarantee long-lasting reliability in environments that experience high pressure, heat, and corrosive substances.
