Alloy 825 is a nickel-chromium-iron-based high-temperature alloy widely employed in the chemical, oil and gas, and nuclear industries due to its exceptional corrosion resistance, high-temperature strength, and machinability.
Chemical Composition and Properties of Alloy825 Nickel-Based Alloy
Composition Design: Nickel (38%-46%) forms the matrix, with chromium (19.5%-23.5%) enhancing oxidation resistance. Molybdenum (2.5%-3.5%) and copper (1.5%-3.0%) synergistically improve resistance to pitting and stress corrosion cracking.
2.4858 Nickel-based Alloy Alloy 825 Nickel AlloyI-825 Alloy Nicr21mo Nickel AlloyPhysical Properties: Density 8.14-8.27 g/cm³, melting point 1370-1400°C. Maintains high strength below 540°C, with ductility significantly decreasing above this temperature.
2.4858 Nickel-based Alloy Alloy 825 Nickel AlloyI-825 Alloy Nicr21mo Nickel AlloyProcessing Characteristics: Cold working enhances strength; weldability is comparable to austenitic stainless steels; suitable for dynamic stress applications such as oil well tubing.
Alloy 825 maintains a tensile strength of 450 MPa at elevated temperatures of 550°C. During welding, a low heat input process (≤30 kJ/cm) is employed with interpass temperature controlled to ≤100°C, ensuring weld corrosion resistance matches that of the base material. It is suitable for demanding environments such as chemical pipelines and offshore equipment.
