Abstract

The invention discloses a composite cold-rolled steel material. The composite cold-rolled steel material is characterized in that the composite cold-rolled steel material is prepared from, by weight,0.2%-0.5% of C, 0.1%-0.5% of Si, 2.0%-2.5% of Mn, 0.01%-0.03% of P, 1.0%-1.5% of Zn, 0.06%-0.1% of S, 0.003%-0.005% of N and 0.13%-0.18% of Ti. According to the composite cold-rolled steel material, the corrosion resistance is high, the strength is high, the stretchability is good, corrosion resistance is achieved, environmental protection and energy conservation are achieved, no pollution is generated, preparation is easy, and therefore the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a composite cold-rolled steel material. Background technique [0002] Cold-rolled steel has good properties, that is, cold-rolled steel strips and steel plates with thinner thickness and higher precision can be obtained through cold rolling, with high flatness, high surface finish, clean and bright surface of cold-rolled steel, and easy to coat There are many kinds of processing and variety, and wide application. At the same time, it has the characteristics of high stamping performance, no aging, and low yield point, so cold-rolled steel tools are widely used. However, cold-rolled steel is often not strong enough, has poor tensile properties, and also causes great pollution to the environment. [0003] The above has become an urgent problem to be solved in the cold-rolled steel industry. Contents of the invention [0004] The present invention aims to solve the above problems and provide a composite cold-rolled steel materi...
