Abstract：

An experimental research was conducted on hydroforming of square section components made of stainless steel Comparison is made between non axial feeding and axial feeding, and loading path, i e relationship between internal pressure, in the hydroforming process of square section components The reason is analyzed for folding, wrinkling and splitting, especially in the transition zone of the section corner The thickness distribution of qualified component is given
