BR440/590HE steel 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.
