38Si7 SKL14 clip for railroad fastening

38Si7 elastic rail clip used with railway sleeper to fasten rails on both sides. The rail clips are usually made of forged spring steel, which are manufactured by hot forging process. The forged rail clips are considered to be better than other metal forming process due to most uniform microstructure.
