|
Super steel has the same chemical composition with plain carbon steel,but its yield strength is higher than plain carbon steel because it has fine grain size.The products of super steel have been used to automobile parts,which not only improves automobile quality,but also reduces the cost and weight of automobile,energy consumption and the environmental pollution.At present,several automobile factories have applied the products of super steel to automobile parts such as,across beam and longitude beam,etc..The appraised standard of drawing properties of steel plate is reviewed.This paper introduces the tensile test,cold bending test and metallographical examination for the super steel sheet that have been done.The tensile test of super steel sheet has been carried out.The machine performances such as,hardening index,value of plastic strain ratio,yield strength,tensile strength,even percentage elongation etc.have been studied and the stamping properties of super steel have been analyzed.The result indicates that super steel has better stamping properties,which has a certain guidance function in the stamping production.
