摘要
用预先热处理的材料生产高强度螺栓,消除了螺栓杆部的热处理变形,降低了生产成本,降低了机械性能的不稳定性,提高了产品质量及螺纹联接的可靠性。
Introduces a new technology on the solts manufacture with primary heat-treatment material.It eliminate s the heat-treatment deformation.The mechanical properties stability,the production quality and the reliability of the screw thread were increased.Produce-cost was reduced.
