250A53/ EN45 Spring Steel- TJC STEEL.

12/2/2020

 
Features And Scope Of Application for 250A53/ EN45 Spring Steel:
Silicon and manganese to improve the elastic strength and flexion ratio, improve hardenability, anti-tempering stability and anti-relaxation stability, overheating sensitivity is smaller, but the decarbonization tendency is larger, especially [TJC STEEL]when silicon and carbon content is higher, carbon is easy to graphitization, make steel brittle.Used as vibration damping plate spring and coil spring, cylinder safety valve spring on automobiles, tractors and locomotives, and also can be used as heat resistant spring under 250℃.
