3CR12 is a corrosion-resisting steel containing approximately 12 % Cr. It was developed in the early 1980s in South Africa and is available in Europe, specified as DIN 1, 4003. <br>Experimental results of full-scale beam tests on the lateral torsional buckling behaviour of recently developed 3CR12 hot-rolled structural sections are presented. Singly and doubly-symmetric hot-rolled sections were investigated. The experimental work was duplicated for 300WA carbon steel sections to use as a direct comparison. <br>The experimental results are compared with theoretically calculated values of the South African code of practice (SANS-10162-1:2005) and the European code of practice (Eurocode 3). The recommended resistance factors are used. Conclusions and recommendations of the possible inclusion into the current code of practices are given.
