Incoloy 925 wire is a high-performance nickel-iron-chromium alloy wire with excellent corrosion resistance and high strength. It is widely used in chemical, marine, energy and medical fields. Its main components include 42%-46% nickel, 19.5%-22.5% chromium, 2.5%-3.5% molybdenum and 1.5%-3.0% copper, which give it excellent resistance to pitting, crevice corrosion and chloride ion stress corrosion cracking.
Incoloy 925 wire has excellent mechanical properties, with a tensile strength of ≥965 MPa, a yield strength of 758-965 MPa, an elongation of 18%-27%, and a hardness of up to 38 HRC. It performs well in both oxidizing and reducing environments, especially in sulfuric acid, hydrochloric acid and marine environments. This alloy wire can be used to make welding wires, spring wires, heat exchanger components, submarine pipelines and medical devices, etc. It is an ideal material for handling high temperatures and corrosive media.
