(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.

3. Basis of Purchase
3.1Orders for material under this specification shall include the following information:
3.1.1Quantity,
3.1.2Name of material,
3.1.3ASTM Designation: A99,
3.1.4Grade,
3.1.5Size, and
3.1.6Requirements for packing, analysis reports, etc., as appropriate.
3.2The customary basis of payment for standard ferromanganese is per pound of ferroalloy, rather than per pound of contained
managanese.Although low- and medium-carbon ferromanganese are ordered by total net weight, the customary basis of payment
is per pound of contained manganese.
NOTE1—The term “weight” is temporarily used in this specification because of established trade usage. The word is used to mean both “force” and
“mass,” and care must be taken to determine which is meant in each case (SI unit for force = newton and for mass = kilogram). General Conditions for
