| Abstract: | To better utilize the products of super steel,which are used to automobile parts to improve the automobile quality and reduce the cost and weight of automobile,energy consumption and the environmental pollution,the evaluation standard of drawing properties of steel plate was reviewed and the effect of tensile test values on stamping properties was introduced.The tensile test of super steel sheet has been carried out.The mechanical performances such as hardening index,value of plastic strain ratio,yield strength,tensile strength and even percentage elongation were studied,and the stamping properties of super steel were analyzed.The result indicates that super steel has better stamping properties and can be widely used in the production of automobile stamping part. |
