The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in JIS carbon steel SM490B CS plate etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.
