/Dual-phase high-strength cold-rolled steel plates and strips. Baosteel implements standards (/ replaces /B). This standard specifies the terms and definitions, classification and codes, dimensions, appearance, weight, technical requirements, inspection and testing, packaging, marking and inspection documents of duplex high-strength cold rolled steel plates and steel strips. This standard applies to dual-phase high-strength continuous cold-rolled steel plates and steel strips with a thickness of .~.3 produced by Baoshan Iron and Steel Co., Ltd. Dual-phase steel ()
The microstructure of steel is ferrite and martensite, and the martensite structure is dispersed in an island shape on the ferrite matrix. Dual-phase steel is age-free, has a low yield-strength ratio and high work-hardening properties. At the same yield strength level, higher-strength low alloys have higher strength and are one of the preferred materials for structural parts.
