Twinning induced plasticity (TWIP) steels are a class of high-strength steels that have been devel-oped for their outstanding ductility and strength properties. TWIP refers to the fact that these steels display an unusually high degree of deformation before fracture due to the formation of twins during deformation. TWIP steels could be used in a variety of industries for structural applications or com-ponents that need to withstand high levels of stress and deformation. This article deals with the de-velopment of high strength with fully austenitic microstructure and high chromium content. Micro-structure, mechanichal and corrosion properties of this steel were studied.
