5、orrect embedded paragraph references (3.5.3.2, 4.2.1.1). 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 product may be supplied directly by a mill or by a producer other than the mill. T
6、he latter would be accomplished by precipitation heat treatment of solution treated material previously certified to AMS5659. The entity assuming responsibility for the aging operation is designated the producer of AMS5659/H1025A. 1.2 Application These products have been used typically for parts req
7、uiring corrosion resistance and high strength up to 600 F (316 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 AMS5659.
