Rotary Flap Peening of Metal Parts

2019-08-26
WIP
AMS2590C
This specification covers procedures and requirements for peening of metal parts with portable, bonded-shot, rotary flap assemblies in accordance with AS2592. The principles of rotary flap peening are similar to conventional shot peening, except conversion of arc height values using the magnetic Almen test strip holder is required for intensity determination.

CURRENT
AMS3414F
This specification covers an aluminum welding flux in the form of powder.
Standard

Inspection of Ground, Chromium Plated Steel Parts

2019-07-18
CURRENT
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.
Standard

Carburizing and Heat Treatment of Carburizing Grade Steel Parts

2019-04-15
CURRENT
AMS2759/7D
This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements and procedures for three classes of gas, vacuum, liquid, and low pressure (LPC) carburizing and related heat treatment of parts fabricated from carburizing grade steels. Parts made from steels other than those specified in the detail specifications may be heat treated in accordance with the applicable requirements using processing temperatures, times, and other parameters recommended by the material producer unless otherwise specified by the purchaser. This specification does not cover pack carburizing.
Standard

Chemical Process Test Specimen Material

2019-03-25
WIP
AS2390A
This standard establishes definitions, guidelines, and requirements governing the specific material (e.g., alloy and heat treat condition) to be used for chemical process test specimens when requirements call for "the same generic class of alloy".
Standard

Anodic Treatment of Aluminum Alloys Sulfuric Acid Process, Undyed Coating

2019-03-25
WIP
AMS2471J
This specification establishes the requirements for undyed anodic coatings on aluminum alloys. This process has been used typically to increase corrosion resistance and to provide surfaces that will promote adherence of paint and other organic finishes, but usage is not limited to such applications. AMS2472 should be specified for coatings colored by dyeing. This process is not suitable for parts that contain joints or recesses in which the anodizing solution may be retained.
Standard

Petroleum Base Instrument Bearing Lubricant, Viscosity 15

2019-03-25
WIP
AMS3055C
This specification covers the requirements for a refined paraffinic petroleum-base lubricant. This lubricant has been used typically in spin axis bearings of gyroscopes, accelerometers, and similar bearing applications, but usage is not limited to such applications.
Standard

Gaseous Nitrocarburizing

2019-03-15
CURRENT
AMS2757C
This specification covers the engineering requirements for producing a continuous thin epsilon-iron-carbonitride compound layer on parts by means of a gaseous, low temperature process, and properties of the case.
