Railway Coupler Striker Alloy Steel Casting

The railway coupler striker is the core load-bearing and impact-resistant component of a railway vehicle's coupler and draft gear system, usually installed in the middle of the underframe end beam of a railway vehicle. It is mainly made of AAR Grade C/E cast steel or specially heat-treated wear-resistant cast steel, and has the characteristics of high strength, excellent impact toughness and reliable load transfer performance. It can withstand huge impact forces, longitudinal loads and repeated friction transmitted by the coupler during train coupling, braking and operation on complex lines, and its performance directly affects the coupling safety, underframe structural strength and running stability of railway vehicles.
