摘要
３０ＣｒＭｎＳｉＮｉ２Ａ 钢Ｍｓ 点以上采用等温淬火工艺， 其强度指标随等温温度升高而降低， 且低于淬火２００℃回火的指标值，而塑性、韧性指标相对于淬火２００℃回火有明显提高，硬度稍有降低。
Being equal temperature quenched above Ms point, 30CrMnSiNi2A steel's strength targets descend along with the rising of temperature and even be lower than the targets of quenching and 200℃ tempering But its plasticity and toughness targets are evidently rising more than the targets of quenching and 200℃ tempering, its hardness are a little lower 30CrMnSiNi2A steel obtains the best group of the performances by equal temperature quenching from 340℃
