The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in carbon steel plates manufacturer sheet 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.
According to its surface quality, pickling carbon steel plates manufacturer sheet sheet steel can be divided into I and N two groups; According to its cup protrusion depth can be divided into ordinary and deep two levels. Application: Mainly used in such as body clock case, flashlight case, instrument case, lamp mouth, automobile brake drum, etc. Steel plate size: thickness of 0.25-2mm.
