phosphorus (P): In general, phosphorus is harmful elements in steel, increased cold brittleness of steel, welding performance deterioration, reduced ductility, so cold bending performance deterioration. Therefore typically require phosphorus content in steel is less than 0.045%, high-quality steel requires lower.
