摘要：Due to the influence of the peculiar material characteristics, austenitic stainless steel bolts are always easy to be locked during disassembly. This is not only seriously affected the service performance of austenitic stainless steel bolts, but also affects the reuse of bolts. In this paper, the main causes and mechanism of the locking of austenitic stainless steel blots in the process of fastening is summarized, and the effective measures containing correct material selection, carefully clean before assembly, spraying loosening agent, thermal expansion method, raw material belt tape winding and development of anti-locking austenitic stainless steel fastening bolt to prevent locking through theoretical analysis and experimental verification are also provided, which is hoped that certain guiding significance can be provided to prevent the phenomenon of bolt locking from the source as far as possible.
