Can anyone tell me what the en equivalent of Aisi 4130 steel is ? I have done a google search and have looked up the tables on the steel equivalent websites and can't find it. It seems to be fairly widely used in america.
4130 is close to 25CrMo4 which is equivalent to 708A25. I think 30CrMo4 is an exact match but it's rarely mentioned so probably even harder to find at best. Does that sound right Al?
EN19 is closer/equivilant to 4140 which'd be 42CrMo4 in eurospeak or 708M40
T45 is close/equivalent to EN14 / 150m19 and is BS S514 / S515 in sheet speak
