Form:

This specification covers a corrosion-resistant steel in the form of bars, wire, forgings, flash welded rings, extrusions, and stock for forging, flash welded rings, or extrusion.

Application:

These products have been used typically for parts requiring corrosion resistance, stress-corrosion resistance, high strength up to 600 °F (316 °C), and good ductility and strength in the transverse direction in large section sizes, but usage is not limited to such applications.

Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP1110 recommends practices to minimize such conditions.

Classification:

Steels covered by this specification are classified as follows:

Type 1 - Steel multiple melted using vacuum-arc consumable electrode process in the final melt cycle

Type 2 - Steel multiple melted using electroslag consumable electrode process in the final melt cycle

When a type is not specified, Type I shall be supplied.
