Differences between Inconel 601 Alloy Plate and Inconel 625 Plate
Inconel 601 plate and Inconel 625 alloy plate are both nickel-chromium alloys that have excellent high-temperature properties, but they have different chemical compositions, so each has advantages and disadvantages. Inconel 601 alloy plate is known for its excellent oxidation resistance, especially at high temperatures, while Inconel 625 plate has excellent strength, weldability, and corrosion resistance, especially in chloride-containing environments.
What are the advantages of Inconel 625 plate?
In addition to high tensile strength, INCONEL 625 alloy plate also has high creep strength, high rupture strength and excellent weldability. These properties make it also suitable for aerospace applications, including duct and exhaust systems, turbine shrouds and seals, and thrust reverser systems.
