High-strength bolts closely follow the rapid development of the machinery manufacturing industry

For a long time, high-strength bolts have been plagued by three major issues: short lifespan, heavy weight, and poor reliability, all of which stem from stress concentration sensitivity. High-strength bolts determine the main connecting function of high-end machinery equipment and are closely related to its service life. Heat treatment is the core of high-strength bolts.

• High-strength bolts are commonly made of high-strength low-alloy steel, ultra-high-strength steel, and high-temperature alloys. With the development of high-end machinery equipment, the strength of alloys used for high-strength bolts will continue to increase. However, the prominent weakness of high-strength materials is the sensitivity of fatigue strength to stress concentration.

• The main failure mode of high-strength bolts is fatigue, which is a form of failure in which cracks or fractures occur in one or several places of the bolt under the repeated action of cyclic stress and strain. This includes the processes of crack initiation and crack propagation. Fatigue is a process of mechanical damage accumulation and delayed failure.

• High-end machinery equipment presents unlimited development opportunities for the manufacturing of high-strength bolts.
