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