6、2.2) and Reports (4.4.7). 1. SCOPE 1.1 Form This specification covers a corrosion-resistant steel in the form of bars, wire, forgings, flash welded rings, and extrusions in the solution heat treated condition (see 8.3) 12 inches (305 mm) and under in nominal diameter, thickness or for hexagons, leas

7、t distance between parallel sides, and having a maximum cross-sectional area of 144 in2(930 cm2), and stock of any size for forging, flash welded rings, or extruding (see 8.6). 1.1.1 For purchase of solution treated and aged product, use the applicable AMS slash specification (see 8.3). If a slash s

8、heet description is not specified, solution annealed material shall be supplied. A specific example of a slash specification is: AMS5659/H1025 Precipitation Hardened to H1025 condition. 1.2 Application These products have been used typically for parts requiring corrosion resistance and high strength

9、 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. 1.2.1 Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking. ARP1110 recommends prac

10、tices to minimize such conditions. 1.3 Classification Products covered by this specification are classified as follows: Type 1 - Steel multiple melted using vacuum consumable electrode remelting. Type 2 - Steel multiple melted using electroslag remelting. SAE INTERNATIONAL AMS5659S Page 2 of 10 1.3.
