Inconel alloy
Features: high performance, high temperature resistance, corrosion resistance, high strength, up to 1100MPa or more, can maintain high strength at high temperature.
Application: widely used in high temperature and high pressure environments such as aircraft engines, and also suitable for corrosive environments.
Hastelloy alloy
Features: high strength, high corrosion resistance, especially able to withstand extreme corrosive environments such as strong acids, strong alkalis, and salts, with a tensile strength of more than 1000MPa.
Application: widely used in chemical, aviation, metallurgy, petroleum and other fields, especially suitable for working environments with corrosive media.
