NON-MAGNETIC AUSTENITIC STAINLESS STEEL HAVING IMPROVED STRENGTH AND SURFACE CONDUCTIVITY

摘要

Disclosed is a non-magnetic austenitic stainless steel with improved strength and surface conductivity. An austenitic stainless steel according to an embodiment of the present disclosure includes, in percent (%) by weight of the entire composition, C: 0.07 to 0.2%, N: 0.15 to 0.4%, Si: 0.8 to 2%, Mn: 16 to 22%, S: 0.01% or less (excluding 0), Cr: 12.5 to 20%, Cu: 1 to 3%, the remainder of iron (Fe) and other inevitable impurities, and satisfies the following equation (1). $\mathrm{Ni}+0.65\mathrm{Cr}+1.05\mathrm{Mn}+0.35\mathrm{Si}+12.6\mathrm{C}+33.6\mathrm{N}\ge 40\mathop{\mathrm{image}}$ Ni, Cr, Mn, Si, C, N are % by weight of each element.
