In this work, the effect of solid soluble temperature, cold treating temperature and ag- ing temperature on the mechanical properties of 0Cr12Mn5Ni4Mo3Al had been inves- tigated systemically. The results show that under the optimal parameters (solid soluble treatment 1050℃×40min, cold treatment -78℃×4h, aging treatment 520℃×2h) the properties (strength and tenacity) could be up to its maximum.
