Form: This specification covers a corrosion-resistant@ precipitation-hardenable steel in the form of bars@ wire@ forgings@ flash welded rings@ and stock for forging or flash welded rings. Application: Primarily for parts requiring corrosion resistance and high strength at temperatures up to 600?? (316??) with good ductility and strength in the transverse direction in large section sizes. Certain processing procedures and services conditions may cause this material to be subject to stress-corrosion cracking; ARP 1110 recommends practices to minimize such conditions.
