Application of hot rolled steel :


The hot - rolled forming steel could be classified into commercial quality ( CQ ) , deep drawing quality ( DDQ ) , and extra - deep drawing quality ( EDDQ ) by its intended application . With low carbon content , excellent drawing and welding performance , high dimension accuracy . Hot rolled forming steels are widely used in many drawing industries .


ApplicationFeatureSteel Grades
Commercial UseWith some ductility , these steel are applied to simple forming , bending or weldingDD11 , SPHC
DrawingWith more ductility than commercial use steels,they are applied to manufacture parts through drawing and relatively complicated formingDD12 , SPHD
Deep DrawingWith more ductility than drawing steels,they are applied to manufacture parts through deep and complicated formingDD13 , SPHE
Extra - Deep DrawingWith more ductility than deep drawing steels , they are applied to manufacture parts through extra - deep and more complicated formingDD14 , SPHF , BRC1 , BRC2 , BRC3

General structure steel has high strength and good formability , it can afford heavy load after common machining . the structure steel has reliable mechanical property , good formability and excellent welding performance , which is widely used in various industries , structure steel can be classified as normal structure steel,welding structure steel , tool steel and pipe steel .
