Product Detail

Overview

Cr30Ni70 is an alloy material with excellent high temperature properties and corrosion resistance. Its high nickel content gives the material good high-temperature strength, while chromium provides excellent oxidation and corrosion resistance. The physical and mechanical properties of Cr30Ni70 enable it to be used in a wide range of high-temperature environments, including metallurgy, chemical, electric heating and aerospace. With the increasing demand for high-temperature materials, the application prospect of Cr30Ni70 will be broader.

Characteristic

Oxidation resistance: Cr30Ni70 alloy can form a stable oxide film at high temperature, effectively prevent the matrix material from reacting with external gases, and is suitable for working at high temperatures for a long time.
Corrosion resistance: It has strong corrosion resistance to acid, alkali and other chemical media, especially in high temperature corrosion environment, and can maintain long-term stable performance.

Application

Electric heating equipment: Used to manufacture high temperature electric heating elements, such as resistance wires and heaters, for high temperature electric furnaces and industrial heating equipment.
Chemical industry: For the production of high temperature and corrosion resistant reactors and pipelines.
Aerospace: Used in high-temperature engine components and thermal barrier materials, especially in turbines and combustion chambers.
Metallurgical industry: Used in high temperature furnace, furnace tube and other high temperature equipment.
