Can anyone help with the yield and ultimate strengths of 4130 steel heat treated to Rockwell C (HRC) in the range of 30 to 35? I am looking to see if it is needed for a new design with a where time is the ultimate constraint on the project.
I found some approximations of ultimate strengths, but not how the yield strength has shifted due to the heat treating.
