Product Overview
Inconel 625 plates are high-performance, nickel-based superalloys renowned for their outstanding resistance to high temperatures, oxidation, and corrosion. These plates are engineered to maintain structural integrity in aggressive environments, making them indispensable in industries such as aerospace, marine, chemical processing, and nuclear power.
The alloy's composition includes a minimum of 58% nickel, 20–23% chromium, 8–10% molybdenum, and 3.15–4.15% niobium, with controlled amounts of iron, titanium, and aluminum. This unique blend imparts exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Additionally, Inconel 625 exhibits excellent weldability and can be easily fabricated using standard techniques.
With a density of 8.44 g/cm³ and a melting point ranging from 1290°C to 1350°C, Inconel 625 plates offer superior thermal stability. Mechanical properties include a tensile strength of 827 MPa, yield strength of 414 MPa, and elongation of 30%, ensuring durability under stress. These attributes make Inconel 625 plates ideal for applications requiring materials that can withstand extreme conditions without compromising performance.
In summary, Inconel 625 plates provide a reliable solution for demanding applications, offering a combination of strength, corrosion resistance, and thermal stability that ensures long-term performance in harsh environments.
