Form This specification covers a corrosion-resistant steel in the form of bars@ wire@ forgings@ and forging stock. Application These products have been used typically for heat-treated parts requiring stress corrosion resistance@ along with a combination of high strength and high toughness up to 800 ??(427 ?? with good ductility and strength in the transverse direction@ but usage is not limited to such applications. Certain design@ processing procedures@ or environmental conditions may cause these products to become susceptible to stress-corrosion cracking; ARP1110 recommends practices to minimize such conditions.
