随着锰含量的增加，13Cr－8Mn－0．08N不锈钢在正人态及500℃回火态的强度和硬度逐渐下降，δ和Ak值逐渐增高，锰含量在6％和7．5％～10％的铬锰氮不锈钢获得最佳综合机械性能的回火温度分别为600℃和500℃。
With the increase of Mn content, the strength and hardness of 13Cr-8Mn-0.08N stainless steel gradually decreased in normal human body and tempered at 500 ℃, and the δ and Ak values gradually increased, and the contents of manganese were between 6% and 7.5% -10 The tempering temperatures for% Cr, Mn and N stainless steels for best overall mechanical properties were 600 ° C and 500 ° C, respectively.
