Fajar Metals, a reputable manufacturer and supplier located in Jakarta, Indonesia, specializes in precision-engineered Incoloy 825 Nuts that are built to endure highly corrosive and extreme environments. These nuts are crafted from a nickel-iron-chromium alloy, enhanced with molybdenum, copper, and titanium, which gives them remarkable resistance to both oxidizing and reducing chemicals. Adhering to standards like ASTM B425 and ASTM B564, Incoloy 825 nuts are perfect for fastening applications in chemical plants, offshore structures, power stations, and marine equipment. Their impressive mechanical strength, corrosion resistance, and durability guarantee secure and long-lasting joint performance in critical industrial systems.
Incoloy 825 Nuts 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 distinctive alloy combination offers resistance against sulfuric, phosphoric, and nitric acids, as well as protection against chloride-induced stress corrosion cracking. With a tensile strength of 585 MPa, yield strength of 220 MPa, and an elongation of about 30%, these mechanical properties make Incoloy 825 nuts ideal for high-pressure and high-temperature fastening, particularly in corrosive industrial settings.
