1、Designation: A601/A601M 10Standard Specification forElectrolytic Manganese Metal1This standard is issued under the fixed designation A601/A601M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in
2、 parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers several grades of electrolyticmanganese designated as follows:GradeRegular AIntermediate Hydrogen BLow Hydrogen C4.5
3、% Nitrogen Bearing D6 % Nitrogen Bearing EWeld Grade Powder F1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. Thevalues stated in each system may not be exact equivalents;therefore, each system shall be used independently of the other.Combi
4、ning values from the two systems may result in non-conformance with the standard.1.2.1 This specification is expressed in both inch-poundunits and in SI units (within the text, the SI units are shown inbrackets); however, unless the purchase order or contractspecifies the applicable M specification

Size5.1 The various grades are available in the sizes listed inTable 3.5.2 The sizes listed in Table 3 are typical as shipped fromthe manufacturers plant. These alloys exhibit varying degreesof friability;
9、therefore, some attrition may be expected intransit, storage, and handling (see 5.3 and SpecificationA1025).5.3 Friability Ratings:Grades A, B, CGrades D, ENo. 6No. 56.
