化学成分对1Cr13钢中铁素体含量的影响

Effect of Chemical Composition on Ferrite Content in Steel 1Cr13

特殊使用条件下的1Cr13叶片型不锈钢要求铁素体含量＜5%。本文从化学成份角度入手,通过半马氏体钢1Cr13中常见元素对铁素体含量影响的分析,结合相关试验数据,提出了解决钢中铁素体含量＜5%的具体办法。

Ferrite content of 1Cr13 for turbine blade in special application must be less than 5%. In this paper, in view of chemical composition, the effect of common elements in half- martonsitic steel 1Cr13 on ferrite content was analyzed. Based on the tested data, the measures to make ferrite content less than 5 % wss suggested.
