ST52-3 low alloy steel is equivalent to domestic brand Q345. St52-3 new material number: 1.0570, old material number: 1.0841. St52-3 takes its tensile strength and yield point as its main characteristics. Q235C carbon steel material products are generally used in the manufacture of various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment used in mining and various engineering constructions And other structural parts.

The thickness of cold-rolled steel sheets is generally relatively small, and the thickness of hot-rolled plates can be larger. The surface quality, appearance, and dimensional accuracy of cold-rolled steel sheets are better than those of hot-rolled plates, and the thickness of cold-rolled steel sheets can be rolled as thin as about 0.18mm. Q235C carbon steel material, Hot-rolled plates has high strength, good toughness, easy processing and good weldability and other excellent properties.

The common delivery status of Q235C carbon steel material, SA516 Gr 70 plate is as follows: 1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point. 2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air). 3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly. 4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.

Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between Q235C carbon steel material, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.
