... (Mo) is also a strong carbide former and is used in a small amount to strengthen low-alloy steels (e.g., Cr-Mo steels). It is unlikely these steels will be affected by MoO 3 -related oxidation problems. However, molybdenum is an effective alloying element for improving the resistance of the alloy to...
