What Standards Cover Material Groups 1018/1020 and 4130/4140
(OP)
Good Day Everyone,
If this question has already been answered then please direct me to the appropriate thread.
I have recently been tasked with reviewing the material grades currently used for our product designs to make sure they have the needed mechanical properties. To accomplish this I have been cross referencing the mechanical properties in the appropriate ASTM Standards to our design calculations.
I am down to my last two groups of materials and I am having trouble locating what ASTM standards cover the mechanical properties of:
1) 1018 / 1020
2) 4130 / 4140
in both flat and round bars.
If ASTM standards do not clearly cover these materials what SAE standards do.
Thank you in advance for all your help.
