(Specification)Standard Specification for Ferromanganese
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 A
Grade B
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 standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
