Investigation on Stamping Properties of 400MPa GradeSuper Steel Sheet
Super steel has the same chemical composition as plain carbon steel, but its yield strength is higher than plain carbon steel due to its finer grain size. The super steel sheets 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 400MPa 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 400MPa grade super steel has been analyzed too. It can be used for guidance of stamping production.
