Features (depending on grades)：
1.Excellent resistance to stress, pitting corrosion, crevice corrosion and localized corrosion at room temperature
2.Superior mechanical properties at room temperature
3.Superior corrosion resistance at elevated temperature
4.Good mechanical properties at elevated temperature
Generally, with more than 30% Nickel content is called nickel base alloy, and the Nickel content of common products is more than 50. According to the properties can be divided into nickel - based heat - resistant alloy and nickel - based corrosion - resistant alloy. Excellent performance, maintain high strength at high temperature, excellent mechanical properties such as creep resistance, corrosion resistance, good plasticity and weldability. Generally, it is used in high temperature environment above 540 degree, mainly for special corrosion resistant environment, high temperature corrosion environment and with high temperature mechanical strength equipment. It is often used in aerospace, energy, petrochemical industry or special electronic, optoelectronic and other fields.
