Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, a516 grade 70 equivalent and so on.

The allowable temperature of a516 grade 70 equivalent, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of a516 grade 70 equivalent work, the actual stress of a516 grade 70 equivalent under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of a516 grade 70 equivalent under the temperature.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of a516 grade 70 equivalent, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).
