Technical Information


  1. 1.

    In manufacturing high-quality gears precisely one-third of the whole tolerance must be allowed for machining and two-thirds for nitrocementation.

  2. 2.

    The dependability and durability of drilling apparatus using nitrocementated gears of steel 30KhGT are far greater than those with nitrided gears of steel 30KhYuA.

  3. 3.

    Nitrocementation is a shorter process than nitriding and nitrocementated gears have higher mechanical properties and less warping than those of nitrided gears.
