EFFECTS OF INCLUSION ON DRAWING PROPERTY OF HP295 CYLINDER STEEL

The influencing factors of drawing properties for the cylinder end-heads were analyzed by checking out the defect of cylinder end-heads which made of HP295 steel.Resultsshow that the crack at cylinder end-heads in drawing process is due to the concentrated RE inclusion in the steel. And its wrinkle defect is related to banding texture in the steel, uneven sheet thickness and drawing parameters.
