  1. 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

      2)TR3775 is the material speficiation of EN4130 not TR3755. TR3775 page 11 contains AM4967.
