Test Research of Stamping Property for 500MPa Grade Super Steel Sheet
Super steel has the same chemical composition as plain carbon steel, but its yield strength is higher than plain carbon steel because it has finer grain size. The products of super steel sheet have been used in automobile parts, which not only improves the quality of the automobiles, but also reduces the cost and weight of automobiles, decreases energy consumption and environmental pollution. At present, several automobile manufacturers have applied the super steel products to their parts, such as Across Beam and Longitude Beam, Automotive wheel, et al. This paper introduces the tensile test, cold bending test and metallographic examination for 500MPa grade super steel sheet that have been done. The hardening index, value of plastic strain ratio, yield strength, tensile strength, even percentage elongation and other mechanical performances have been studied. The press forming performance of 500MPa grade super steel has been analyzed too. It can be used for guidance of stamping production.
