Steel Bars, Forgings and Tubing, 0.50Cr - 1.8Ni - 0.25Mo (0.17 - 0.23C) (SAE 4320H)

2018-09-20
WIP
AMS6299G
This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.These products have been used typically for parts to be carburized requiring high minimum core hardness with wide range in sections 0.375 inch (9.5 mm) and under in thickness, but usage is not limited to such applications. The core may or may not be machinable after hardening.

Electroless Nickel Plating, Low Phosphorus

2018-09-20
WIP
AMS2405F
This specification covers the engineering requirements for electroless deposition of low-phosphorus nickel on various materials and the properties of the deposit.
Standard

Phosphate Treatment, Paint Base

2018-09-20
WIP
AMS2480J
This specification covers the requirements for producing a zinc phosphate coating on ferrous alloys and the properties of the coating. This process has been used typically to produce a coating that will ensure satisfactory paint adherence, but usage is not limited to such applications.

Fuel Filter Test Methods

2018-09-20
WIP
J905
The purpose of this fuel filter test method is to provide standardized methods for evaluating the performance characteristics of fuel filters by bench test methods. This, combined with data obtained from application tests, may be used to establish standards of performance for filters when tested by these standard methods. Many variations in requirements of filtration to protect fuel supply equipment on engines and variations in operating conditions make it difficult to specify meaningful "in-service" performance standards by which a filter may be judged. By the use of these standard test methods, test conditions are always the same, and comparisons of the laboratory performance of filters may be made with a high degree of confidence. Once the requirements of a particular application are known, performance standards for suitable filters may be established by these test methods, and adequacy of performance of filters for the job may be determined.

Etch Inspection of High Strength Steel Parts

2018-09-20
WIP
AMS2649E
This specification establishes the requirements for etch inspection of bare high strength low alloy steel parts having tensile strength of 180 ksi (1241 MPa) and higher and of carburized parts to detect overheating caused by abusive machining or grinding in the heat treated condition, and to detect localized discontinuous carburization. This process is not applicable to surface hardened steels produced by nitriding or carbonitriding. This process may remove 0.0001 to 0.0005 inch (2.5 to 12.7 micrometers) from the surface of the part.
Standard

Inspection of Ground, Chromium Plated Steel Parts

2018-09-20
WIP
AMS2440C
This specification covers the requirements for inspection of ground chromium plated surfaces for grinder-induced damage to the chromium plate and substructure. The specification also provides users with criteria for distinguishing between such damage and acceptable indications inherent to the chromium plate.
