surface traverse

Surface hardness of bearing steet decreased after quenching, because temperature traverse quickly in cooling-off The case happens easily when the time of steam film is longer and the temperature of quenching oil is lower.

轴承钢油淬后往往发生表面硬度偏低，其原因是因为冷却途中冷速急剧变化引起的，特别是在蒸汽膜期长，特征温度低的油中淬火时更易发生。
