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. For purchase of solution treated and aged product@ use the applicable AMS slash specification (See 8.5). If a slash sheet description is not specified@ solution annealed material shall be supplied. A specific example of a slash specification is: AMS5629/H1000 ?C Precipitation Hardened to H1000 condition Application These products have been used typically for parts requiring corrosion resistance@ stress-corrosion resistance@ high strength up to 600 ??(316 ??@ 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: Melting Practice 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. Maximum Delta Ferrite Content Class A ?C 0.5% max.@ free ferrite Class B ?C 1.0% max.@ free ferrite Class C ?C 2.0% max.@ free ferrite When no class is specified@ any class may be supplied.
