ASTM A482/A482M-11(2021)
(Specification)Standard Specification for Ferrochrome-Silicon
Standard Specification for Ferrochrome-Silicon
ABSTRACT
This specification covers ferrochrome-silicon of Grades A and B. Chemical analysis shall be performed wherein specimens shall conform to required chemical composition of chromium, carbon, silicon, sulfur, phosphorus, nitrogen, manganese, nickel, vanadium, copper, molybdenum, columbium, tantalum, cobalt, aluminum, titanium, zirconium, arsenic, lead, tin, zinc, boron, antimony, silver, and bismuth.
SCOPE
1.1 This specification covers several grades of ferrochrome-silicon.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.2.1 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply.
1.2.2 Within the text, the SI units are shown in brackets.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
