Scope

This specification specifies the engineering requirements for heat treatment, by part fabricators (users) or their vendors or subcontractors, of parts made of cast nickel or cobalt alloys and of fabricated assemblies in which cast nickel or cobalt alloys are the primary structural components. This specification is not intended to provide requirements for heat treating operations that are a responsibility of the casting supplier in meeting the requirements of the casting commodity specification.

Rationale

AMS2773F results from a Five-Year Review and update of this specification with the addition of ordering information, added furnace Class 5 and Type D instrumentation to pyrometry (3.1.1), added revised partial pressure and leak rate requirements to vacuum furnaces (3.1.2.2), revised amount of material removed from heating media (3.1.2.3), revised cleaning such that purchaser shall supply clean parts in prior to heat treatment (3.2.1.1), revised racking requirements regarding small parts (3.2.2), revised offset temperature selection in control instruments (3.2.3), changed start of soak for batch furnaces to align with AMS2759 (3.2.5.1), changed start of soak for vacuum furnaces to align with AMS2769 (3.2.5.2), changed start of soak for continuous furnaces such that verification is preproduction (3.2.5.3), revised re-heat treatment from being allowed twice to once (3.2.7), added cycle interruption requirements (3.2.8), clarified hardness (3.5.2), added rework and cycle interruptions to report/certification (4.7), and added note 8 to Table 3 stating tolerances for heat treatment temperatures.
