Form This specification covers a corrosion-resistant steel in the form of bars@ wire@ forgings@ mechanical tubing@ flash welded rings up to 8.0 inches (203 mm) in diameter or least distance between parallel sides@ and stock of any size for forging@ flash welded rings or heading (see 8.7). For purchase of solution treated and aged product@ use the applicable AMS slash specification (see 8.4). If a slash sheet description is not specified@ solution annealed material shall be supplied. A specific example of a slash specification is: AMS5643/H1025 ?C Precipitation Hardened to H1025 condition. Application These products have been used typically for parts requiring corrosion resistance and high strength up to 600 ??(316 ??@ but usage is not limited to such applications. Certain processing procedures and service conditions may cause these products to become susceptible to stresscorrosion cracking; ARP1110 recommends practices to minimize such conditions. For applications@ such as bolting@ where stress-corrosion is a possibility@ the product should be precipitation heat treated for not less than 4 hours at the highest temperature compatible with the strength requirements but in no case lower than 1025 ??(552 ??.
