含铬超过13%的铁素体不锈钢在400-550℃的温度范围内加热时，会发生严重的脆化，称为475℃脆化。一些关于二元铁铬合金这一现象的实验和评论论文已经发表。另一方面，在其他合金元素存在的情况下，475℃脆的发生没有得到充分的研究。根据Baerlecken和Fabritius的结果，强碳化物形成物（钛和铌）略微增加了脆化。Mima等人对高钒含量的影响进行了研究。他们发现钒降低而不是增加了脆化。本文介绍了少量钒含量对17% Cr钢475℃脆化的影响。
Ferritic stainless steels containing more than 13% chromium are subject to severe embrittlement, known as the 475° C embrittlement, when heated in the temperature range of 400–550° C. Several experimental and review papers have been published about this phenomenon concerning binary iron–chromium alloys. On the other hand, the occurrence of the 475° C embrittlement in the presence of other alloying elements is not thoroughly studied. According to the results of Baerlecken and Fabritius, strong carbide formers (titanium and niobium) slightly increase the embrittlement. The effect of high vanadium contents was studied by Mima et al. They found that vanadium decreases rather than increases the embrittlement. This note refers the effect of small vanadium contents on the 475° C embrittlement of a 17% Cr steel.
