  9. Minimum time to harden a thin blade - Heat Treating Knives q690e hardening

    They tend to be very deep hardening, so it surprised me when you said (and I verified via the data sheet) that N690 is listed as an oil quench steel. The oil quench recommendation may be for much thicker cross-sections than a typical knife.

  10. Bohler-Udderholm Heat treating N690

    Bohler-Udderholm Heat treating N690. Now the way I understand plate quenching is that blades are heated to the relevant hardening temperature in the furnace / kiln then removed but rather than quenching in oil, are clamped between two steel or aluminium plates which draw the heat out of the blade, while keeping the blade straight.

  11. HEAT TREATMENT OF BLADE STEEL - KMTS

    Process: Hardening is a way of making the knife steel harder. By first heating the knife steel to between 1050 and 1090C and then quickly cooling (quenching) it, the knife steel will become much harder, but also more
