通过对链条用40Mn带钢淬火硬度不均的调查分析,认为C、Mn含量低及用户不合适淬火工艺是淬火硬度不均的主要原因,为此针对厚规格链片开发出40Mn-1,并协助用户调整淬火工艺。
Through the analysis of 40Mn steel strip quenching unevenness of the chain, it is considered that the low content of C and Mn and improper quenching of the user are the main reasons for the unequal quenching hardness. For this purpose, 40Mn-1 Assist the user to adjust the quenching process.
