The paper discusses the specific phenomena of global stability of members from metallic non-linear materials with a special focus on ferritic stainless steel. Here, an alternative calculation of reduction factors is introduced considering the material non-linearity, especially hardening parameters. This theoretical assumption for the buckling behaviour of stainless steel members is supported by numerical study presented in the paper and the suitability of the new model is tested by regression analysis in comparison with the commonly used standard approach. The analysis results show that our approach could be successfully applied in flexural, torsional-flexural and lateral-torsional buckling.
