Introduction
Inconel 725 plate is a high-performance nickel-based superalloy that exhibits excellent corrosion resistance and high strength, making it suitable for applications in the oil and gas, marine engineering, chemical processing, and high-temperature sectors.
Advantage
High Strength - Precipitation hardening provides tensile strength ≥ 860 MPa and yield ≥ 690 MPa, ensuring durability under heavy loads.
High-Temperature Stability - Niobium and titanium stabilize the microstructure, keeping strength and shape under heat and pressure.
Good Fabrication Performance - The plate can be hot-rolled, cold-rolled, machined, and welded for complex components.
