The effects of Ni and N addition to 304 stainless steel on mechanical properties and microstructure were investigated within temperature ranged from $-196^{circ}C$ to $25^{circ}C$. The addition of nickel and nitrogen induced the stability against the formation of provide significantly enhanced ductility at $-196^{circ}C$ and reduce the Md temperature. Fe-18Cr-10Ni-0.2N alloy showed the ${gamma}$ phase in deformed structure which it was beneficial to enhance the tensile strength and elongation at $25^{circ}C$ and $-196^{circ}C$.
