Embodiment Construction
[0074] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0075] For the composition of the steel plate in the embodiment of the present invention, refer to Table 1, and Table 2 to Table 5 show the manufacturing process of the steel plate in the embodiment of the present invention. Table 5 shows the performance parameters of the steel plates of the embodiments of the present invention.
[0076] Depend on figure 1 From the microstructure of the steel plate in Example 3 of the present invention, it can be seen that the microstructure of the steel plate is fine and uniform pro-eutectoid massive ferrite+low carbon lower bainite (the ultra-low carbon bainite in this figure is the fire state), the comprehensive mechanical properties and weldability of the steel plate in Example 3 are extremely good, and have reached the technical requirements of the invented steel plate.
[0077] In summary, the present invention ...
