在先进的9%到12%的铬钢中，铬当量被用作检查δ铁素体形成的一种手段。在本分析中，对29种不同成分的合金进行了真空感应熔炼，并在回火条件下测量了δ铁素体的数量。在此基础上，结合前人对9~12%铬钢的研究结果，提出了一个新的铬当量计算公式，并将其与δ铁素体的生成量进行了关联。结果表明，新的铬当量方程具有较好的相关性，并能较好地预测δ铁素体的生成量。
In advanced 9 to 12 pct Cr steels, the Cr equivalent is used as a measure to check the formation of δ-ferrite. In the present analysis, 29 alloys of varying composition were vacuum induction melted, and the amounts of δ-ferrite were measured in as-tempered conditions. Based on this and previous results on 9 to 12 pct Cr steels, a new equation for the Cr equivalent is proposed and correlated with the amount of δ-ferrite formation. Results indicate that the new Cr equivalent equation shows better correlation than previous equations and predicts the amount of δ-ferrite formed reasonably well.
