Niobium rod introduction
Niobium rod is a metal material, usually used in manufacturing processes under high temperature and high pressure environment. Niobium rod has the characteristics of high strength, high temperature oxidation resistance and excellent corrosion resistance. Niobium rod is a very important industrial material, widely used in aviation, aerospace, nuclear energy and other fields.
Niobium rod appears white fracture blue
In the process of using niobium rod, it is often found that niobium rod appears white fracture blue. This phenomenon usually occurs in high temperature and high pressure environment. For example, in high temperature environment, niobium rod is affected by oxidation reaction, and white fracture blue will appear. Moreover, after repeated use in high temperature and high pressure environment, the surface of niobium rod will also show obvious oxidation phenomenon, which will lead to the performance decline of niobium rod.
