Nial Sheets and Plates is a reliable manufacturer and supplier of Inconel 625 Coil and Slitting Coil based in Houston, USA. They specialize in providing high-performance nickel-based alloy products designed to withstand extreme service conditions. Inconel 625 is particularly renowned for its outstanding resistance to oxidation, pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. Nial offers a variety of Inconel 625 Coils in different thicknesses and widths, including custom slit-to-width options, all crafted with precise dimensional tolerances, a superb surface finish, and excellent flatness. These coils find extensive applications in the aerospace, marine, chemical, and energy sectors, where mechanical strength and corrosion resistance are crucial.
The composition of Inconel 625 Coil and Slitting Coil includes about 58% nickel, 20–23% chromium, 8–10% molybdenum, and 3.15–4.15% niobium, along with trace amounts of iron, cobalt, and other alloying elements. These coils boast impressive tensile strength (~827 MPa), yield strength (~414 MPa), and remarkable resistance to fatigue, creep, and rupture. The alloy remains mechanically stable from cryogenic temperatures all the way up to 1000°C, effectively resisting both oxidizing and reducing environments.
