Q420q steel material is a kind of structural steel plate for bridges, the grades are Q420qD, Q420qE, Q420qF.Q420q steel chemical composition: C: ≤0.11, Si: ≤0.55, Mn: 1.0-1.7, Nb: 0.01-0.09, V: 0.01-0.08, Ti: 0.006-0.03, Cr: ≤0.50, Ni: ≤0.30, Cu: ≤0.30, N : ≤0.008, Al: 0.01-0.045.Steel delivery status: delivered in the thermomechanical rolling state, and the steel plate should be trimmed for delivery.
Different form BV grade E traffic boat steel, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.
Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and BV grade E traffic boat steel steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and BV grade E traffic boat steel medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
