BR450/780DP steel

BR450/780DP steel

BR450/780DP has many advantages such as good formability, high strength, low yield ratio, high initial work hardening rate, good balance of strength and ductility, etc. It is a solution to the problem that the high- strength low-alloy steel is not easy to punch. Dual-phase steel is suitable for manufacturing parts of complex shapes, such as car wheel discs and other components.
