重型六角螺栓由高强度钢制成,或者需要较大预紧力的螺栓也可以称为高强度螺栓。高强度螺栓主要用于桥梁,钢轨,高压和超高压设备的连接。这种螺栓的断裂大多是脆性断裂。为了确保容器的密封,需要对用于超高压设备的高强度螺栓施加预应力。

如今,以大型飞机,大型发电设备,汽车,高速火车,大型船舶和大型成套设备为代表的先进制造业已进入重要的发展方向。结果,紧固件将进入重要的发展阶段。高强度螺栓用于连接重要的机械。反复拆卸或使用各种安装扭矩方法都需要极高强度的螺栓。

 因此,表面状况和螺纹精度将直接影响主机的使用寿命和安全性。为了提高摩擦系数并在使用过程中避免腐蚀,卡死或卡住,技术要求规定表面应进行镍磷电镀处理。涂层厚度保证在0.02〜0.03mm范围内,涂层均匀,致密,无针孔。

重六角螺栓必须根据技术要求进行淬火和回火。热处理和回火是为了提高紧固件的综合机械性能,以满足规定的拉伸强度值和产品的屈服比。热处理工艺对高强度紧固件具有至关重要的影响,尤其是其内部质量。因此,为了生产高质量的高强度紧固件,需要先进的热处理技术和设备。
