This specification covers two grades of premium aerospace grade corrosion resistant steels available in the form of bars, wire, forgings, and forged stock. The products are in the solution heat treated condition. The products covered by this specification are limited to nominal diameter or maximum cross-sectional dimension between parallel sides (thickness) not exceeding 6.00 inches (152.4 mm), unless the product is tested in the H1000 condition (see 3.5.1.2 and 8.7). When the product is tested in the H1000 condition, the product is limited to nominal diameter or maximum cross-sectional dimension between parallel sides (thickness) not exceeding 8.00 inches (203.2 mm). Forged stock may be of any size. These products are generally used for parts requiring corrosion resistance and high strength up to 800°F (427°C). The steel may be precipitation hardened to a minimum tensile strength of up to 225 ksi (1551 MPa). Certain designs and processing procedures may render these products susceptible to stress corrosion cracking after heat treatment; ARP1110 recommends practices to minimize such conditions. The steels covered by this specification are classified as follows: Grade 1: Transverse ductility, not specified Grade 2: Transverse ductility, specified Unless a specific type is ordered, Grade 1 shall be furnished for products having a nominal diameter or the shortest distance between parallel sides less than 3.00 inches (76.2 mm); Grade 2 shall be furnished for larger sizes.
