ASTM A983\/A983M-06-Reapproved2021<\/h3>\n

Active Standard: Standard Specification for Continuous Grain Flow Forged Carbon and Alloy Steel Crankshafts for Medium Speed Diesel Engines<\/h4>\n
\n

ASTM A983\/A983M<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This specification covers continuous grain flow forged carbon and alloy steel crankshafts for medium speed diesel and natural gas engines.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> The steel used in the manufacture of the forgings is required to be vacuum degassed.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> The choice of steel composition grade for a given strength class is normally made by the forging supplier, unless otherwise specified by the purchaser.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> Provision is made for treatment of designated surfaces of the crankshaft to provide enhanced fatigue strength, or wear resistance, or both.<\/p>\n<\/p><\/div>\n

\n

1.5<\/span> Except as specifically required in this specification, all provisions of Specification A788\/A788M<\/span> apply.<\/p>\n<\/p><\/div>\n

\n

1.6<\/span> Unless the order specifies the applicable \u201cM\u201d specification designation, the material shall be furnished to the inch-pound units.<\/p>\n<\/p><\/div>\n

\n

1.7<\/span> The values stated in either inch-pound units or SI (metric) units are to be regarded separately as standard. Within the text and tables the SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.<\/p>\n<\/p><\/div>\n

\n

1.8<\/span> 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.<\/i><\/p>\n<\/p><\/div>\n
