Ferrous Sulfide
Ferrous sulfide is mainly used in casting industry. Adding a certain amount of sulfur to gray cast iron can improve the cutting performance, the inoculation effect and the morphology of graphite. Sulfur can shorten the length, blunt the end and bend the morphology of graphite, so adding sulfur can also improve the mechanical properties of gray cast iron. The sulfur element can be effectively controlled within the range of 0.08%-0.12%.

Sulfur plays a double role in the production of cast iron. It makes the castings brittle under certain conditions, so that it can cause surface defects and slag defects to reduce mechanical harmfulness. It can also enhance the mechanical property of gray iron castings especially low-sulfur gray iron castings and increase the group number of eutectic and number of nodular iron castings.
