Form: This specification covers a corrosion and moderate heat resistant@ precipitation-hardenable steel in the form of sheet@ strip@ and plate. Application: Primarily for parts requiring corrosion resistance and high strength up to 600?? (315??)@ and where such parts may require welding during fabrication. Certain design and processing procedures may cauae these products to become susceptible to stress-corrosion cracking; ARP 1110 recommends practices to minimize such conditions.
