Q420 steel is a low-alloy high-strength structural steel. Q420 steel is not only a high-strength steel, but also a low-carbon steel. It's just that the tensile strength of Q420 steel has increased a little.
Due to the low carbon content of Q420 steel, it cannot be quenched and tempered, and it is still impossible to process shafts and gears. However, Q420 steel is very good for making steel plates, and its strength is much higher than that of Q235 steel.
Q420 steel has high strength and good fatigue resistance; Q420 steel has high toughness and low brittle transition temperature; Q420 steel has good cold forming performance and welding performance; Q420 steel has good corrosion resistance and certain wear resistance.
Q420 steel is suitable for power towers, various types of lifting cranes, heavy vehicles, oil derricks, high-temperature fans, large electric shovels, dump trucks and drilling rigs, coal mine hydraulic supports, steel structures, etc.
