Compared with carbon steel, alloy steel plate is a steel plate with other alloy elements added to the material, and the material performance is more excellent. Compared with other steel plates, alloy steel plates have outstanding performance. First, 20MnB5 boric steel, alloy steel plate has higher strength, stronger bearing capacity, less breakage when bearing large objects, and longer service life. Second, alloy steel plate has good corrosion and wear resistance. In the open air environment, the steel selected for road and bridge paving must have high corrosion resistance and wear resistance, otherwise it will be damaged after a period of use and it will easily lead to accidents.
20MnB5 boric steel controlled rolling is that, on the basis of adjusting the chemical composition of 20MnB5 boric steel, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of 20MnB5 boric steel.
