Material and application of high strength stud bolt
High strength stud bolt is used for mechanical fixed link function. Both ends of the stud bolt have threads, and the screw in the middle has thick and thin ones. It is called straight rod or shrinking rod, also called double head screw.
Material of high strength stud bolts:
The materials of high strength stud bolts are 35 #, 45 #, 35CrMoA, 25Cr2MoV, 304, 316, 304L, 316L, 2h, 2hm, B7, b7m, B16, B8, 8, b8m, 8m.
Application of high strength stud bolts:
1. High strength stud bolts are used in large-scale equipment, which need to install accessories, such as mirrors, mechanical seal seat, reducer frame, etc. This is the stud bolt used. One end is screwed into the main body, and the other end is equipped with a nut after the accessories are installed. Because the accessories are often disassembled, the thread will be worn or damaged, so it is very convenient to replace the stud bolt.
2. High strength stud bolts are used when the thickness of the connector is very large and the length of the bolt is very long.
In the actual work of high-strength stud bolt, the external load vibration, change, high-temperature creep of material will cause the reduction of friction, the positive pressure in the thread pair disappears in a moment, and the friction is zero, so that the thread connection is loose. If it is repeatedly acted, the thread connection will be loose and fail. Therefore, it is necessary to prevent loosing, otherwise it will affect the normal work and cause accidents.
