Molybdenum is added to low-alloy steels to increase which property?

Explanation:
Molybdenum increases hardenability in low-alloy steels, which means the steel can develop harder microstructures during heat treatment even in thicker sections. By slowing theTransformation of austenite during quenching and promoting martensite formation deeper inside the piece, the steel attains higher hardness measured at room temperature. Molybdenum also forms stable carbides (such as Mo2C) that resist deformation, further boosting hardness and wear resistance. While it also helps with high-temperature strength and creep resistance, the direct reason this question points to is the enhanced hardness achieved through better hardening during heat treatment.
