The non-metallic inclusions of the hot-rolled EN steel grade S420NL material steel sheet are elongated bands, which are not well combined with other metals. Therefore, compared with the anisotropy that can be observed from the shape and size of the crystal grains, the steel sheet has a larger potential The anisotropy results in poor ductility perpendicular to the rolling direction. The internal anisotropy of the EN steel grade S420NL material cold-rolled steel sheet can be alleviated by annealing.

Hot rolled EN steel grade S420NL material product stock size: 12*1600*91000, 25*1950*10250, 25*1950*10150, 14*2000*10000, 12*1600*10000, 16*1500*9340, 60*2020*6100, 25*1950*9700, 14*2000*13500, 75*2390*4320, 16*1500*9340, 50*2740*13460, 20*2100*10700, 20*2500*6200, 60*1750*9100, 34*1900*12000, 12*2050*5100, 45*2010*10000, 25*2100*8650, 70*2270*7600, 16*1500*9340, 6*1950*10000, 30*2000*7630, 20*2100*11600, 70*2260*7950, 34*1900*12000.

Common specifications for cold-rolled plates: thickness 0.2-4mm, width 600-2000mm, length 1000-6000mm.Commonly used grades: Q19-Q23, Q19F-Q23F, Q29(B)-Q345 A(B); SPCC, SPCD, SPCE, DC01-06.Because rolling at room temperature does not produce iron scale, the cold-rolled sheet has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical and technological properties are better than hot-rolled thin steel sheets EN steel grade S420NL material. In many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets."

The related factors of EN steel grade S420NL material steel plate cutting are mainly steel plate material, steel plate specific use and steel plate cutting requirements, so it can be said that there are many related factors. Different processing methods, such as finish machining and rough machining, choose different EN steel grade S420NL material steel plate cutting methods. Wire cutting or plasma cutting is used for finishing and flame cutting is used for rough machining. Therefore, it can be concluded that the steel plate cutting methods selected under different processing methods are different.
