Characteristics of nickel-based alloys

Nickel-based alloy is one of the most widely used and strongest superalloys. The name superalloy derives from the material characteristics.

These include:

(1) Excellent performance: It can maintain high strength at high temperature, and has excellent mechanical properties such as resistance to submersion and fatigue, as well as oxidation and corrosion resistance and good plasticity and weldability.

(2) Super complicated alloy addition: nickel base alloy often adds more than ten alloying elements to improve the corrosion resistance of different environments; And solid solution strengthening or precipitation strengthening.

(3) Extremely harsh working environment: Nickel-based alloy is widely used in a variety of harsh working conditions, such as the high-temperature and high-pressure part of the gas chamber of aerospace engine, the structural parts of nuclear energy, petroleum, Marine industry, corrosion resistant pipelines, etc
