High-strength Dual-phase Galvanized Steel Sheets and Coils
High-strength Dual-phase Galvanized Steel Sheets and Coils have the characteristics of no yield elongation. They also show a low yield ratio which means low elasticity and precise size. Additionally, they have a high hardening index and baking hardening value.
Thus, it is one of the preferred materials for automotive panel structural components. For example,they are used to manufacture automobile structural parts, reinforcements and anti-collision parts (e.g. cross members of underframe, rails, bumper reinforcing structural part), automobile inner and outer panels and engine hood panels, etc. Thus, they have an extremely wide application prospect.

Application
Due to the rapid cooling of low-carbon and low-alloy duplex steel, DP steel has a low yield to strength ratio. It also features a high solidification rate and rapid initial hardening. Hence, Dp steel is the preferred choice for structural components. These components include automotive crossbeams, tracks, crash bars, and reinforced structural parts.
