EN 3523: 2024 / Aerospace series - Steel 15CrMoV6 (1.7334) - Air melted - Hardened and tempered - Bars for machining - De ≤ 100 mm - 1 080 MPa ≤ Rm ≤ 1 280 MPa

Heat Treatments

  • Hardened and tempered (U): heating within range 955 - 995°C, air cooling or oil quenching; + heating within range 615 - 655°C, air cooling.
  • <b>Hardened and tempered (U)</b>: heating within range 955-995°C, oil or water quenching; + heating within range 595-645°C, air cooling.<br />A stress relief tempering between quenching and tempering could be done at 350°C minimum in order to avoid risk of quenching crack.
