... curve with as-quenched steel hardness is to use quench factor analysis (QFA) ( Ref 9 ). This method has been used to successfully predict as-quenched hardness for carbon steel and a limited number of low-alloy steels, including AISI 4130 ( Ref 10 ), 4140 ( Ref 10 , 11 ), 1045 ( Ref 10 , Ref 12...

Higher-carbon steels such as 1090 can be successfully martempered in oil due to lower M s temperature and the additional time...

The more alloying elements hinder carbon to diffuse, the higher the hardenability will be, because more time is available to reach the martensite start temperature (M s ) further inside where the cooling rate...
