Abstract
Austenite-austenite plus δ ferrite phase boundaries have been determined for the Cr-Ni-Mn-N system at temperatures of 2100°, 2200°, and 2300°F over the composition ranges 15 to 21 pct Cr, 0 to 3 pct Ni, 12 to 18 pct Mn, and 0.25 to 0.45 pct N. The structural diagrams permit the selection of ferrite-free stainless compositions containing little or no nickel.
