ASTM A100-07
(Specification)Standard Specification for Ferrosilicon
Standard Specification for Ferrosilicon
ABSTRACT
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.
SCOPE
1.1 This specification covers grades of ferrosilicon for steelmaking and foundry uses.
1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units (SI units) given in parentheses may be approximate.
