This paper by R Cruise and L Gardner was published in the Journal of Constructional Steel Research, Volume 64 Issue 11, November 2008. It discusses the strength enhancements induced during cold forming of stainless steel sections. The material properties of stainless steel are sensitive to plastic deformation. Unique strength distributions from different forming techniques influence the residual stress patterns. This paper presents results from experiments measuring stress distributions in cold rolled box sections and press braked angles. It is concluded that cold rolling creates strength enhancements that should be considered in structural design to avoid considerable underestimation of member resistance.
