The main process of elastic rail clips production is blanking, intermediate frequency heating, stamping forming, oil quenching, intermediate temperature tempering, shot peening, and anti-corrosion treatment. In order to ensure the performance and metallographic structure of elastic rail clips, it is required that the hardness after quenching should reach HRC60. The hardness after tempering should be HRC44-48. The elastic strip shall not be broken after 3 to 5 million fatigue tests, and the residual deformation shall not exceed 1.0mm.
The quenched structure is mainly martensite with a small amount of residual ferrite and small pieces of bainite, and must meet the level specified by the standard. The tempered structure should be uniform tempered troostite and tempered sorbite. I hope you can use this information to increase your understanding of elastic rail clips.
