Chuck Metals stands out as a top manufacturer and supplier in Singapore, specifically on Pulau Ujong, where they offer high-quality Incoloy 825 Forgings. These forgings are celebrated for their remarkable corrosion resistance, making them perfect for a variety of tough environments. Crafted from a nickel–iron–chromium alloy with added molybdenum, copper, and titanium, they are designed to perform exceptionally well against both oxidizing and reducing media. Chuck Metals prides itself on precision craftsmanship, strict adherence to international standards, and a range of shapes and sizes, which makes Incoloy 825 Forgings a go-to choice for demanding sectors like chemical processing, oil & gas, marine, and pollution control equipment.
Incoloy 825 Forgings are composed 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%). They boast a tensile strength of around 550 MPa and a yield strength of 220 MPa, along with excellent ductility, ensuring they maintain their mechanical stability across a wide temperature range. The unique chemistry of this alloy provides strong resistance to sulfuric and phosphoric acids, seawater, and stress-corrosion cracking.
