摘　　要：通过对紧固件30CrMoA钢制活节螺栓普通淬火和锻热淬火的试验研究,对普通淬火和锻热淬火进行力学性能比较,并且对锻热淬火试件进行组织分析,锻热淬火在力学性能上不低于普通淬火,综合性能有所改善,所以对于30CrMoA钢制活节螺栓进行锻热淬火是可行的,现已经用于生产。Through the research of general quencher and Forge-Quenching to the 30CrMoA steel ball head bolt, this paper compares the mechanics function of the sample after general quencher Forge-Quenching, and carries on the analysis of the organization to the sample after Forge-Quenching, the test shows that the Forge-Quenching is no lower than the common quencher on the mechanics function, and the synthesize function has improvement, so the Forge-Quenching is viable to the 30- CrMoA steel ball head bolt. It has already been used for the production now.
