How to choose the material of bolts and nuts?
May 28, 2021| Many customers ask questions like: How to choose the materials of bolts and nuts? Obviously, customers like this don't know much about the raw materials of nuts. If you have any questions, please call our sales number!
The difference between the mechanical function requirements of bolts and nuts is:
① The mechanical function of the nut mainly depends on the hardness of the nut, the height of the nut, and the wall thickness of the nut. Therefore, the requirements for materials are not high. Of course, if the nut has a resistance requirement, higher-level materials should also be used, such as chemical industry Fasteners and nuts have requirements for durability, which rules higher-level data.
②The higher the functional level of the plastic target required by the bolt, the higher the level of material can be reached. The lower level of material only needs to reduce the tempering temperature to reach the strength requirements, but it cannot meet the requirements of plasticity and resistance. In fastener testing , Brittle fracture is judged to be unqualified. Steel structure bolts are also regulated with higher tensile strength, in order to ensure the plastic resistance of the bolts.
