PRODUCT PARAMETERS:

The main causes of soft spots in ATV gears are:

1, the ATV gear metallographic arrangement is not uniform, such as the presence of carbide segregation, ribbon arrangement or large ferrite in the steel. In this case, before quenching should be cast or appropriate preparation of heat treatment, is arranged as homogenized as possible.

2. The surface of the ATV gear is partially decarburized or the surface carbon concentration is uneven after the gear carburizing, and the low carbon area becomes a soft point after quenching.

3, quenching medium cooling capacity is insufficient, such as water mixed with oil or soap and other impurities, easy to make the beach car gear soft point.

4. Improper operation, such as the appearance of the workpiece of the ATV gear is unclean, and the oxidation skin or dirt is not sorted out; The workpiece immersed in the quenching medium, insufficient movement, etc., will form soft points.
