SAE AMS 5617J pdf download.Steel,Corrosion-Resistant, Bars, Wire, and Forgings 12Cr – 8.5Ni -1.2Ti – 2.0Cu Vacuum Induction Plus Vacuum Consumable Electrode Melted Solution Heat Treated,Precipitation Hardenable.
1.1 Form
This specification covers two grades of a premium aircraft-quahty, corrosion-resistant steel in the form of bars, wire, forgings, and forging stock.
1.2 Application
These products have been used typically for parts requiring corrosion resistance and high strength up to 800 F (427 SC).
The steel can be precipitation hardened to minimum tensile strengths up to 225 ksi (1551 MPa).
1.2.1 Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking after heat treatment: ARP1 110 recommends practices to minimize such conditions.
1.3 Classification
Steels covered by this specification are classified as follows:
Grade 1: Transverse ductity, not specified
Grade 2: Transverse ductility, specified
1.3.1 Unless a specific type Is ordered, Grade 1 shall be supplied for product under 3,00 inches (76,2 mm) in nominal diameter or least distance between parallel sides, and Grade 2 shall be supplied for larger sizes.
2. APPLICABLE DOCUMENTS
The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein The supplier may work 10 0 subsequent revision of a document unless a specific document issue Is specifIed. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply.
