AMS5659/H1025C Steel, Corrosion-Resistant, Bars, Wire, Forgings, Rings, and Extrusions 15Cr - 4.5Ni - 0.30Cb (Nb) - 3.5Cu Consumable Remelted, Solution and Precipitation Heat Treated (H1025)

AMS5659/H1025C is the result of a Five-Year Review and update of the document. The revision prohibits unauthorized exceptions (1.1, 3.5.3.5, 4.3.4, 5.1, 8.4), revises heat treatment and stress relief (3.4.1, 3.4.2, 8.5), adds strain rate limits (3.5.3.1.1), adds footnotes to Table 1, removes redundant requirements (3.5.3.1.1, 3.5.3.1.2), adds a requirement for conformance to AS6279 (1.1.1, 3.8), updates tolerances and reporting (3.7.1, 4.3.1, 4.3.2), allows prior revisions (8.3), and aligns the document with the other precipitation heat treatment specifications for this alloy.
