This specification covers a corrosion and heat-resistant nickel alloy in the form of round, square, and flat wire 0.500 inch (12.70 mm) and under in nominal diameter or thickness, capability tested in a No. 1 temper condition.
AMS5698H is the result of a Five-Year Review and update of the specification. The revision updates the title, scope, and response to heat treatment (1.1, 3.3.3) to clarify the purchased material condition, prohbitis unauthorized exceptions (3.3.4, 3.6, 4.4.2, 5.2.3, 8.5), updates composition reporting (3.1.1), adds continuous heat treatment and pyrometry controls (3.2), clarifies reduction requirements (3.2.2), adds strain rate requirements for tensile testings (3.3.1), adds country of origin requirements (4.4.1), corrects Table 6B conversions, updates definitions (8.2), and allows prior revisions (8.4).
