Steel, Extra High Toughness, Corrosion-Resistant, Bars, Wire, Forgings, Rings, and Extrusions, 13Cr - 8.0Ni - 2.2Mo - 1.1Al, Vacuum Induction Plus Consumable Electrode Melted, Solution Heat Treated, Precipitation-Hardenable
This specification covers an extra high toughness, corrosion-resistant steel in the form of bars, wire, forgings, flash welded rings, extrusions 12 inches (305 mm) and under, and stock of any size for forging, flash welded rings, or extrusion.
Rationale: AMS5934A revises the document to allow the purchasing of heat treated material (1.1.1), prohibits bar being cut from plate (18.104.22.168.1 & 4.4.8), clarifies solution treat holding times (3.4), revises macrostructure (22.214.171.124), provides for properties outside the specified size range (126.96.36.199.2.1, 4.4.4). requires short transverse tensile testing when possible (188.8.131.52.2.3), deletes hardness testing (184.108.40.206, 4.2.2), and revises reports (4.4).
