摘要

To investigate the effect of heat treatment on delayed fracture resistance of high strength steel, 30MnSi steel bars with different heat-treatments are produced. Tensile results showed that, the annealing and sub-temperature quenching steel bars have good delayed fracture resistance and satisfy the criteria that delayed fracture does not occur in 200 h, but there is a marked drop in delayed fracture resistance when the quenching temperature is higher than sub-temperature quenching.
