This specification covers a corrosion-resistant steel product 8 inches (203 mm) and under in nominal diameter, thickness or for hexagons least distance between parallel sides, and having a maximum cross-sectional area of 64 in2 (413 cm2) in the solution and precipitation heat treated (H1025) condition.
Rationale:
AMS5643/H1025B prohibits unauthorized exceptions (1.1, 3.4.1.3.5, 3.8, 4.3.4, 5.1, 8.4); revises title; limits bar from plate (3.2.2, 4.3.3); revises stress relieving (3.3.2, 3.6, 4.3.1, 8.5); updates precipitation heat treatment specification and process (3.3.1); adds strain rate (3.4.1.3.1.1); adds a requirement for conformance to AS6279 (1.1.1, 3.7); updates reporting (4.3); allows prior revisions (8.3); and is a Five-Year Review and update of this specification.
