Inconel is a type of high-performance alloy with nickel as the main component. It has excellent high temperature resistance, corrosion resistance and mechanical properties and is widely used in extreme environments.
1. Main components
Nickel (Ni): The content is usually above 50%, providing good corrosion resistance and high temperature strength.
Chromium (Cr): The content is 14-23%, enhancing oxidation resistance and corrosion resistance.
Iron (Fe): The content is low and used to adjust mechanical properties.
Molybdenum (Mo), niobium (Nb), **Ti)**, etc.: Improve strength, corrosion resistance and high temperature performance.
2. Performance characteristics
High temperature resistance: Maintain excellent mechanical properties and oxidation resistance at high temperatures.
Corrosion resistance: Good resistance to corrosive media such as acids, alkalis, and salts.
High strength: High strength and toughness in both high and low temperature environments.
Fatigue resistance: Good fatigue resistance under cyclic loads.
3. Common grades
Inconel 600: Suitable for high temperature and oxidation resistant environments, commonly used in heat treatment equipment and chemical industry.
Inconel 625: With excellent corrosion resistance and high strength, suitable for marine and chemical environments.
Inconel 718: High strength, creep resistance, widely used in aerospace and gas turbines.
4. Application areas
Aerospace: used for engine parts, turbine discs and combustion chambers, etc.
Energy industry: used for nuclear reactors, gas turbines and petrochemical equipment.
Chemical industry: used for corrosion-resistant reactors, heat exchangers and pipelines.
Marine engineering: used for seawater treatment equipment and submarine parts.
