Which material has better high temperature mechanical properties, 1Cr20Ni14Si2 and 0Cr25Ni20? Which material has good high-temperature wear resistance?
The former uses relatively high C to increase high-temperature strength, and the latter uses relatively high Cr to increase high-temperature strength. However, the high-temperature performance is not only the strength, but also includes other physical properties such as creep properties. Generally speaking, the higher the CrNi alloy element, the better the high-temperature performance.
