There are ASTM specifications where you can find a general list of low alloy steels such as A322, where only the compositions are shown, but if you need a SMYS (minimum specified) you need a code or specification that specifies a minimum required, maybe the use or More information on this could be useful.
In the following links you can find properties for both steels in different heat treatment conditions and when you open each one, the Key Words section offers you the main specifications that fit the material in that condition, I hope it will be useful.
4140
1018
If you have more information, we are waiting for you here.
By the way, a question as open as that seems schoolwork, is it?

Different specs will have different HT and strength requirements.
