Applied in fluidized bed temperature monitoring. High temperature wear、 corrosion-resistant alloy,is practiced under mills、 fluidized bed etc harsh conditi***,is fully verified and has good results of wear resistace;is superior to the life of traditional material several times,anti-erosion and can bear corrosion、high temperature and has outstanding performance; it can use wear-resistant material of different performance for different conditi***, which resolves better frequent problems of damage brought by traditional crafts, reduces maintenance costs. Thermal conductivity performance and coefficient of thermal expansion are equal to stainless steel.
