Nut, Self-Locking - Steel, Class 1100 MPa/235 °C, MJ Thread Procurement Specification For, Metric (Stabilized: Dec 2021) 公制MJ螺纹1100 MPa/235°C级自锁钢螺母采购规范（稳定:2021年12月）

发布日期： 2021-12-28

本规范规定了以下类型自锁螺母的要求:a.扳手螺母:即六角、双六角、花键传动B。锚定螺母:也就是说，板形螺母、组合槽形螺母、柄形螺母。扳动螺母和柄形螺母由低合金钢制成，板形螺母和组合槽形螺母的螺母元件由碳钢或低合金钢制成，并具有符合ISO 5855/2的MJ螺纹。螺母在室温下的抗拉强度等级为1100 MPa。235℃时零件的最高试验温度。

This specification establishes the requirements for the following types of self-locking nuts:a. Wrenching nuts: that is, hex, double hex, spline driveb. Anchor nuts: that is, plate nuts, gang channel nuts, shank nutsThe wrenching nuts and shank nuts are made of low alloy steels, and the nut elements of plate and gang channel nuts are made of carbon steels or low alloy steels and having MJ threads to ISO 5855/2. Nuts have 1100 MPa tensile strength class at room temperature. Maximum test temperature of parts at 235 ¿¿C.
