Standard Specification for GRAY IRON CASTINGS
|Publication Date:||22 November 1976|
|ICS Code (Iron and steel castings):||77.140.80|
This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration (Note 1). Castings are classified on the basis of the tensile strength of the iron in separately cast test bars.
NOTE 1-Gray cast irons are those in which free graphite is present in the form of flakes.
This specification subordinates chemical composition to tensile strength.
Where there is a conflict between this specification and a written exception, such as a detailed purchase order, -a purchase specification, or a product specification, the exception shall take precedence over this specification.
NoTE 2-The values stated in U.S. customary units are to be regarded as the standard.
