ASTM A99-03

Standard Specification for Ferromanganese

ABSTRACT
This specification covers standards for ferromanganese (Grades A, B, and C), medium-carbon ferromanganese (Grades A, B, C, D, and nitrided) and low-carbon ferromanganese (Grades A and B). The ferroalloys shall conform to manganese, carbon, silicon, phosphorus, sulfur, and nitrogen contents specific to different material grades. Materials shall also adhere to content limits of arsenic, tin, lead and chromium. The material shall be available in standard sizes, tolerances, and friability ratings.
SCOPE
1.1 This specification covers ten grades of ferromanganese, designated as follows:Standard ferromanganese Grade AGrade BGrade C Medium-carbon ferromanganese Grades A,B,C, and D Nitrided Low-carbon ferromanganese Grade AGrade B
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
