Influence of stamping parameters on stamping characteristics of SAF2205 bidirectional stainless steel

Abstract

SAF2205 bidirectional stainless steel is an excellent material for multiple corrugated diaphragms. It is necessary to study its stamping forming characteristics and provide a theoretical basis for stamping forming of multiple corrugated diaphragms. In this paper, the detailed V-bending process parameters are formulated. The effects of bending speed, relative fillet radius, temperature, and alignment time on spring-back behavior of SAF2205 bidirectional stainless steel are systematically studied to reveal the positive and negative spring-back mechanism. The range of process parameters suitable for stamping of SAF2205 bidirectional stainless steel was obtained. Article Highlights The detailed V-bending process parameters are formulated. The effect of SAF2205 parameters on the spring-back behavior was studied. The range of process parameters suitable for stamping of SAF2205 was obtained.
