Q420 steel is a low-alloy high-strength structural steel. The executive standard of Q420 steel is GB1591-2008, GB16270-2009.
Q420B high-strength angle steel is used as a substitute material for Q235 angle steel and Q345 angle steel. Q420B high-strength angle steel can effectively reduce the design weight of the tower by increasing the material strength, thereby saving materials and reducing transportation and installation costs. Q420B high-strength angle steel plays an extremely heavy role in 750kV, 1000kV and other ultra-high voltage power transmission and transformation system towers.
Q420B high-strength steel is widely used in power towers, various cranes, heavy trucks, oil derricks, high-temperature fans, large electric shovels, dump trucks and drilling rigs, coal mine hydraulic supports, steel structures, etc.
Q420B angle steel has high strength performance, and Q420B angle steel has good fatigue resistance. The tensile strength of Q420B angle steel is also high. Q420B angle steel has high toughness and low ductile-brittle transition temperature, and Q420B angle steel has good cold forming performance and welding performance. Q420B angle steel has good corrosion resistance and certain wear resistance.
