The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, hot rolled plate,s ucha as Q420 steel , has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.
Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. Q420 steel has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. Q420 steel is suitable for power tower, all kinds of crane, heavy truck, oil derrick, high temperature fan, large electric shovel, dump truck and drilling rig, coal mine hydraulic support, steel structure, etc.
