Strengthening of austenitic ({gamma}) stainless steel is of great interest to utilization for the structural component. Strengthening of the steel is attained by a combination of following mechanisms such as solution strengthening, strengthening by grain size effect, strain hardening, and precipitation hardening. A selection for the strengthening of {gamma} steel is precipitation hardening due to carbides, nitrides, and intermetallic phases, by which both high strength and low permeability of {gamma} steel may be satisfied. Among Mo, Ti, V, and Nb carbides, it is known that vanadium carbide is considered to be potent contributor to hardening because it precipitates finely in the matrix and grow relatively slower. However, carbide precipitation hardening behavior of highly alloyed {gamma} stainless steel has not been much studied. In this paper, hardening behavior of the vanadium added, low permeability {gamma} stainless steel, Fe-Cr-6Ni-10Mn-V-C, was investigated focusing on the microstructural change and compositional aspects.
