3. TECHNICAL REQUIREMENTS:
3.1 Composition: Shall conform to the following percentages by weight, determined by wet chemical methods in accordance with ASTM E354, by spectrographic methods in accordance with Federal Test Method Standard No. 151, Method 112, or by other analytical methods approved by purchaser:
3.1.1 Check Analysis: Composition variations shall meet the requirements of AMS 2268.
3.2 Condition: As cast.
3.3 Casting:
3.3.1 The metal for castings shall be melted and poured under vacuum without loss of vacuum between melting and pouring.
3.3.2 Castings shall be poured either from remelted metal from a master heat or directly from a master heat. In either case, metal for casting shall be qualified as in 3.4.
3.4 Master Heat Qualification: Each master heat shall be qualified by evaluation of chemical analysis and tensile specimens conforming to 3.4.1 and 3.4.2, respectively. A master heat may be considered conditionally qualified if vendor’s test results show conformance to all applicable requirements of this specification. However, except when purchaser waives confirmatory testing, final qualification shall be based on purchaser’s test results. Conditional qualification of a master heat shall not be construed as a guarantee of acceptance of castings poured therefrom.
