Sulfur (S): sulfur is usually harmful elements. Hot brittleness of the steel produced, reducing the ductility and toughness of the steel, causing cracks in the forging and rolling. Sulfur is also detrimental to the welding performance and reduce corrosion resistance. So often it requires a sulfur content of less than 0.055%, 0.040% or less than the requirements of high-quality steel. Join 0.08-0.20% sulfur in the steel can be improved machinability, commonly referred to cutting steel.
