2、025 is a new specification for purchase of corrosion-resistant steel product in the solution and precipitation heat treated condition. 1. SCOPE 1.1 Form This specification covers a corrosion-resistant steel product in the solution and precipitation heat treated (H1025) condition. 1.1.1 The aged prod
3、uct may be supplied directly by a mill or by a producer other than the mill. The latter would be accomplished by precipitation heat treatment of solution treated material previously certified to AMS5622. The entity assuming responsibility for the aging operation is designated the producer of AMS5622
4、/H1025. 1.1.2 This specification covers product up to 8.0 inches (203 mm) in diameter or least distance between parallel sides, and forging stock of any size (See 8.2). 1.2 Application These products have been used typically for parts requiring corrosion resistance and high strength up to 600 F (316
5、 C) with good ductility and strength in the transverse direction in large section sizes, but usage is not limited to such applications (See 8.1). 1.3 Classification Melting practice classification shall be in accordance with AMS5622. 2. APPLICABLE DOCUMENTS The issue of the following documents in ef
6、fect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been s
7、pecified, the last published issue of that document shall apply. _ SAE Technical Standards Board Rules provide that: “This report is published by SAE to advance the state of technical and engineering sciences.
