Anotace textu normy ASTM A982/A982M-10(2020) :
This specification covers stainless steel forgings for compressor and turbine bucket, blade, and airfoil applications. The stainless steel shall be made by the melting process and either the closed impression die or the open die forging processes may be utilized. Two complete heat treatments, consisting of an austenize, quench, and temper, are permitted. When heat treatment for mechanical properties is followed by straightening, a stress-relieving heat treatment is required. The forgings shall be subjected to tension, impact, hardness, and non-destructive tests. All forgings shall be free of cracks, seams, laps, shrinkage, and similar discontinuities.

1.1 This specification covers stainless steel forgings for compressor and turbine bucket, blade, and airfoil applications. 1.2 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M designation (SI units), the inch-pound units shall apply. The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, 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. 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. |
