Hakan Nickel Alloys, located in Istanbul, Turkey, is a well-respected manufacturer and supplier of high-quality Incoloy 825 Nuts. These nuts are designed to provide outstanding corrosion resistance and mechanical strength, even in the most challenging environments. With a strong focus on quality and precision, Hakan Nickel Alloys ensures that their Incoloy 825 Nuts meet international standards and align with customer specifications. They cater to various industries, including chemical processing, marine, power generation, and aerospace, delivering reliable and durable fastening solutions that can handle extreme temperatures, corrosive conditions, and mechanical stresses.
Incoloy 825 Nuts are made up of a unique blend of materials, primarily nickel (38–46%), iron (up to 39%), and chromium (19.5–23.5%), along with molybdenum (2.5–3.5%), copper (1.5–3.0%), and trace amounts of titanium and aluminum. This specific composition gives them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in acidic and chloride-rich environments. On the mechanical side, they boast high tensile strength, excellent toughness, and maintain their structural integrity across a broad temperature range. Their well-balanced alloy content guarantees dependable performance, even under thermal cycling and harsh chemical exposure.
