The main raw materials are molten iron and scrap steel. The sulfur and phosphorus content in steel is higher than that of high-quality carbon structural steel, with sulfur ≤ 0.050% and phosphorus ≤ 0.045%. The content of other alloying elements brought into steel by raw materials, such as chromium, nickel, and copper, generally does not exceed 0.30%. According to composition and performance requirements, the grades of such steel are represented by steel grades such as Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275, etc.
