Mechanical properties of steel N14Kh5M3TYu after heat treatment

  • 16 Accesses


  1. 1.

    Quenching from 820°C, usually recommended for maraging steels, does not make it possible to obtain the optimal properties for steel N14Kh5M3TYu. The highest ductility and toughness are attained by quenching from 950–980°C.

  2. 2.

    The optimal combination of strength, ductility, and toughness results from quenching from these temperatures and aging at 480–520°C.

  3. 3.

    Repeated aging results in an additional increase of the strength beginning at temperatures of 300°C and continuing up to the primary aging temperature (480–520°C), which may be due to some differences in the kinetics and composition of precipitates that depend on the original condition of the solid solution before aging.
