    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.

    1. 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



    Low-carbon ferromanganese

    Grade A
