Based on present experimental formulae to calculate martensite starting temperature Ms of various steel grades, with analysis on the effect of alloying elements on Ms of steel, the experiential formula Ms = 550-330C-35Mn-17Ni-12Cr-21Mo-10Cu-5W-10Si-0Ti+10Co+30Al for maraging stainless steel is given in this paper.

本文依据马氏体时效不锈钢的化学成分及实测Ms温度，利用现有的Ms温度计算公式进行分析计算，提出新的马氏体时效不锈钢的Ms温度计算公式。1 现有Ms温度经验计算公式的分析影响钢的Ms点的因素很多，如化学成分、淬火冷却速度、奥氏体化条件、形变等[2 ] 。

It has successfully resolved the net with muffle furnace difficult to solve many technical problems, such as the three muffle heat-resistant steel cans were short-lived, maintenance difficulties and quenching brightness inadequate capacity carburizing poor.

它成功的解决了有马弗网带炉难以解决的许多技术难题，如马弗罐等三大耐热钢件寿命短、维修困难和淬火光亮度不足、渗碳能力差等问题。

It solved many difficult technical problems which the Muffle mesh belt furnace solves with difficulty, for instance, the Muffle pot and so on three big refractory steel's life are short, servicing is difficultand quenching radiance is deficient, carburizing ability is weak and so on.
