Abstract

The static and cyclic mechanical properties of cold-rolled corrosion-resistant VNS 9-Sh (23Kh15N5AM3-Sh) TRIP sheet steel from two batches having different deformation martensite contents in the surface layer are studied. An increase in the deformation martensite content is shown to cause an increase in the strength properties, a certain decrease in the plasticity, and an increase in the fatigue limit at 10⁷ cycles.
