What is the hardness of railway clip
Oct 13, 2025
The rail elastic clip is used for fastening the rails and the tie plate on concrete sleeper. Using the material of forged spring steel, rail clips are produced by hot forging process.
The hardness of a railway clip is typically between 41 and 48 HRC (Rockwell Hardness C scale), achieved through a heat-treatment process to give it the necessary strength and durability. This hardness range ensures the clip can withstand the repeated stress from passing trains without breaking or deforming excessively.
