The difference between use and performance of hot rolled flat steel and longitudinally cut flat steel is discussed
Hot rolled flat steel (hot rolled flat steel strip):Mostly produced by small factories, the raw material sources are disordered and the material can not be guaranteed. Therefore, the mechanical properties of hot-rolled flat steel are greatly different. Hardness, tensile strength, elongation, weldability are often unpredictable.
Its manufacturing process determines the poor dimensional accuracy of hot-rolled flat steel.Vertical shearing flat steel (fine shearing flat steel strip):The raw material board is produced by a larger factory, the raw material source is controllable, the material can be basically guaranteed, and the mechanical performance can basically meet the relevant GB standards.The dimension of vertical shear flat steel is relatively high.
