Terms and Definitions
. Dual-phase steel (D)
The microstructure of steel is ferrite and martensite. The martensite structure is dispersed in an island shape on the ferrite matrix. . Dual-phase steel without aging has a low yield-strength ratio and high work-hardening properties. At the same yield strength level, high-strength low alloys have higher strength and are one of the preferred materials for structural parts. Shanghai Wangyu Industrial Co., Ltd. is mainly engaged in the business and trade of automobile steel products. The company's products include automotive cold-rolled sheets, automotive galvanized sheets, automotive pickled sheets, automotive pipes and other high-end automotive steels, aiming to provide customers with the most perfect automotive steel solutions. The company provides free samples
The price is reasonable and the starting price is one piece. Contact person: Huang Haiming Tel:
