Welding A36 steel to 4140 steel advice needed

Jun 04, 2015· I think Allens rright, hardened 4140 is an insane idea. how hard or its rockwell may play a factor. ETD150 i think is pretty close to a prehardened 4140, and i''ve gotten away w/ welding that, when trying hard, but wouldnt do it on anything formal w/ a consience. but i''ve used 7018 w/ good results w/ 4140 before the oven. i mean really good.
