Such steel must while ensuring that the chemical composition and mechanical properties. Its sulfur (S), phosphorus (P) impurity element content is generally controlled 0.035% or less. If the controlled 0.030% or less were called high quality steel, which should be added behind grade "A", for example, 20A; if P control 0.025%, S controlled 0.020% or less, said the premium quality steel, which should be added behind the grades "E" to show the difference from the raw materials into steel for the other residual alloying elements such as chromium.
