Product description: 

 Product Name: hardened and tempered steel plate (Q420B) 

 Model: 1500-thickness 8mm-65mm width 4020mm length 3000mm-27000mm The largest single steel weighing 35 tons. 

 Origin: Baosteel Wuhan Iron and Steel Wuyang Iron and Steel and Angang TISCO 

 Main purposes: 

 Is a high strength low alloy structural steel. Q420 is not a high-strength steel, it is low-carbon steel. Its tensile strength is increased that the tensile strength of Q235's 235N/MM ^ 2, while the Q420 tensile strength 420N/MM ^ 2 due to its low carbon content can not be quenched and tempered processing, or can not be processed shaft, gears, etc.. But it is made of steel plate is good, the intensity is much higher than the Q235. Q420 with high strength, good fatigue performance; high toughness and low brittle transition temperature; good cold forming and welding properties; better engage in corrosion and wear resistance. 

 Q420 adapted to the power tower, various types of cranes, heavy-duty vehicles, oil derrick, high temperature fan, large shovel, dump trucks and drills, coal mine hydraulic support, steel
