Hi,
42CrMOS4- What is the heat treatment condition Normalised or Quenched and Tempered.
Stregth will not be criteria for welding of these materials. You can use E 7018 or E 8018 electode. You have to preheat of 200 C and post heat of 300 C for 30 min to avoid hydrogen induced cracking.
If you donot want preheat and post heat, you can use E 309L or E 309L MO-16.
Regards
N.V . PRASAD
