Abstract

The ferritic stainless steel is one of the potential materials for manufacturing bipolar plates with good corrosion resistance and low cost. However, due to its poor formability at room temperature, cold stamping process is insufficient to form microchannels. In this work, the mechanical properties of ultra-thin ferritic stainless steel 446 are investigated via high-temperature uniaxial tensile tests. Results show that the strength of ferritic stainless steel 446 at 800 ℃ decreases significantly and the elongation increased by approximately 114% compared with that at room temperature. Hence, hot stamping experiment is conducted at 800 ℃ to verify the feasibility of the hot stamping process for ferritic stainless steel microchannels. Ultimately, the hot stamping process is capable of forming microchannels at 800 ℃.
