Mechanical properties of the high strength steel-23MnNiMoCr54 were studied in this paper, the load-displacement curve was got by the static tensile test and the true stress-strain curve was calculated based on the data. Simplified symmetric finite element elastic-plastic contact model was built based on nonlinear finite element analysis software ABAQUS. Reasonable stress field of the chain and the percentage elongation of the chain were calculated, which were in good accordance with the test results. The mechanical properties of the chain, the finite element model and results provide useful guidance for the design and test of the chain. Source

Differential tempering test was carried out on a repaired single link in the chain using medium frequency induction heating. After differential tempering, the functional properties of the single link keep consistent with that of other links that have already been heat treated in the chain. Properties of the adjacent links remain unaffected and the quality and reliability of the entire chain are enhanced. Source
