对低淬透性的大型锻件直接采用亚温淬火后,其冲击性能改善不大.但经调质处理后,再采用亚温淬火,可以大大提高这类锻件的冲击性能.

Uses directly the sub-temperature quenching to large forgings with low hardenability, its impact performance cannot be improved. But after quenching and tempering to it, then using the sub-temperature quenching may enhance the impact performance greatly.
