Comments to the QTR
1) Could you please be so kind to introduce the Heat treatment curves for the different heating processes?
2) I have checked the material designation (DTM104J, AMS 4928U, AMS4967L) listed on the material supplier COC.
I could not find one of them in TR3755 which is referenced on standard EN 4130.
Best regards
Heinrich Hackmann
