- SAPH440 and Q235 these two materials are automotive sheet metal,through the experiment on mechanical properties, microstructure and bulge forming ability have a comparative study between them. The experimental results showed that: SAPH440 mechanical performance is better than that of Q235,it has small, uniform microstructure grain and strong bulge forming ability. This suggests that the forming performance of SAPH440 is better than Q235. With the rapid development of automobile industry, The design concept of "safety, environmental protection, energy saving" for cars with material and forming technology is put forward higher requirements. Sheet metal forming technology mainly includes the separation process and plastic deformation process, Separation process is a part of the material is separated from the whole or partial separation, Mainly including blanking, punching and trimming, cutting, etc, The plastic deformation process is the external force is applied to deform the material to achieve the desired shape, Mainly including stretching, bending, twisting, curling, spinning, flanging, bulging, etc. Automotive sheet metal formability is refers to the board's ability to adapt to forming technology, formability of sheet metal forming process directly affects productivity, product quality and production costs. Automotive sheet metal formability is related to the forming process, and related to the material of the indicators. Under the condition of process conditions are relatively stable, forming quality depends largely on the performance of the material, So the automotive sheet metal forming performance index is very important. In this paper,there has a comparative study on mechanical performance, organization performance, shape deformation, bulging between automotive sheet metal SAPH440 and Q235 through experiment, it provide experimental evidence for automotive sheet metal stamping process.
