Are you looking for the 20CrMo steel pipe? Katalor is a famous steel exporter and supplier in China. We have high quality 20CrMo steel pipe in our warehouse. And we always export 20CrMo steel pipe more than 35,000 ton every month. Today Katalor will introduce the Influence factors on oxidation resistance of 20CrMo steel pipe at high temperature.
Influence of Cr. In terms of mechanical properties, Cr can not only improve the corrosion resistance of 20CrMo steel pipe metals, but also improve the oxidation resistance. When the content of the 20CrMo steel pipe reaches 13, the corrosion resistance and thermal strength of the 20CrMo steel pipe can be improved significantly. Cr can significantly improve strength, hardness and wear resistance of bonded and tool steels. Cr can improve the oxidation resistance and corrosion resistance of 20CrMo steel pipe.
Effect of Mo on properties of 20CrMo steel pipe. Mo is a carbide forming element with strong carbon affinity. When its content is low, it is mostly dissolved in the cementite and forms alloy cementite. When the content is high, it may form new special carbide. The alloy carbide has an important influence on the properties of 20CrMo steel pipe.
