The estimation of carbon (C), sulfur (S), silicon (Si), manganese (Mn), and phosphorus (P) in cast iron and steel is critical for material classification and quality. Cast iron typically contains 2% or more carbon, while carbon steels have phosphorus levels ranging from 0.035% to 0.040% and sulfur levels from 0.040% to 0.050%. In stainless steels, phosphorus can range from 0.040% to 0.045%, and sulfur can be as low as 0.030%. ASTM A159 cast iron specifies a maximum phosphorus content of 0.12% and sulfur content of 0.15%, indicating that P and S are impurities, whereas C, Si, and Mn are essential alloying elements.
