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.

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.
1. Scope
1.1 This specification covers ten grades of ferromanganese, designated as follows:
| Standard ferromanganese | Grade A |

| Grade C |
| Medium-carbon ferromanganese | Grades A,B,C, and D |
| Nitrided |
| Low-carbon ferromanganese | Grade A |
| Grade 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.
