Description
Product features: A small amount of Nb, Ti, V and other alloy elements are added in low carbon steel, so that it can form carbide and nitride with carbon , nitrogen and other elements, and precipitation in the ferrite matrix, so as to improve the strength of steel; Through precipitation strengthening and fine grain strengthening, higher strength grades can be obtained while the content of alloying elements is reduced.
Performance characteristics: good formability and high strength, the product has a certain aging performance.
Main application: used in structure parts such as car seats and beam etc

Description
Microstructure: mainly martensite and ferrite. The martensite is distributed on the ferrite matrix as an island, and the ferrite is soft , so that the steel has better formability. The stiffer martensite gives steel higher strength. The strength increases with the proportion of hard martensite.
Performance characteristics: no yield platform, no room temperature aging, low yield ratio, high work hardening index and high baking hardening value.
Main application: Hot dip galvanized DP series steel are first choice for structural-parts at present , It is applied to structural parts, reinforcement parts and anti-collision parts, such as beams, longerons, anti-collision rods and other strengthening structural parts.
