WebFeb 25, 2024 · Data from [9] So if the steel had 1%Mn the Mn multiplying factor would be about 1.75, and a factor for 0.5% Si would be about 1.22. Using the factors for C, Mn, and Si then, the factors are multiplied together: 0.61*1.75*1.22 = 1.3 which gives a relative, approximate value for hardenability.
