Sep 10,2013·We need to remember that all heats of any low-alloy steel such as 4140 do not respond to quenching the same.Some require much faster cooling for a given thickness,and vice-versa.The elements that have the strongest effect are C,Mn,Mo and Cr for 4140.Whenever you buy alloy steels,try to get a CMTR-certified mill test report- with it. results for this questionIs there a maximum hardness level for 4140?Is there a maximum hardness level for 4140?The maximum hardness that can be obtained in any steel depends on carbon content.The section size in which maximum hardness can be obtained depends on alloy content.4140 has a nominal carbon content of .4% and this carbon content will yield a hardness of Rc 51for a 90% martensitic structure (9th Edition of the ASM Material Handbook,Volume I).Hardness of Heat Treated 4140 - Metal and Metallurgy
