This specification covers grades of ferrosilicon used for steel-making and foundry. The grades shall conform to the required chemical composition for silicon, carbon, sulfur, phosphorous, aluminum, manganese, calcium, and boron. Sizes available of ferrosilicon for various grades are specified. Ferroalloys exhibit varying degrees of friability; therefore, some attrition may be expected in transit, storage, and handling. Chemical analysis of the material shall be made.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
