PROPRIETARY N2711M Heat Treatments


  • Annealing: Heat slowly and evenly to temperatures between 660 and 680°C, at a rate of 100°C/h, keeping 1 hour for every 25 mm of the largest section of the piece. Cool slowly in an oven (30°C/h) to 500°C, then cool in calm air.

    Stress Relief: After machining with large material removal, stress relief is recommended, heating the molds slowly and evenly (100°C/h) up to 480/500°C, keeping half hour at temperature for every 25 mm of the highest section in the piece, regardless of the section, the time must not be less than 2 hours. After relief, cool in calm air.

    Hardening: During hardening, the surface of the molds must be protected against decarburization and oxidation. Heat slowly and evenly at (100°C/h) to 400°C and then at a maximum of 300°C/h until the austenitizing temperature, between 890 and 910°C. Keep at temperature until complete homogenization of the entire piece. Cooling must be carried out in oil suitable for quenching, stirred and heated between 40 and 70°C, until the mold temperature reaches 100°C. Then cool in calm air to approximately 60°C.

    Tempering: Temper immediately after quenching, as soon as the molds reach 60°C. Make at least 2 tempers and between each temper the parts must cool slowly to room temperature. The tempering temperature must be chosen according to the desired hardness.The time of each tempering must be at least 2 hours. For pieces larger than 70 mm, the time must be calculated as a function of their dimension.
