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.

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.

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.

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.
Standard

Rotary Flap Peening of Metal Parts

2019-01-04
CURRENT
AMS2590B
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.

Hydrogen Embrittlement Relief (Baking) of Steel Parts

2018-10-18
CURRENT
AMS2759/9E
This specification covers the requirements for embrittlement relief (baking) of heat treated steel parts to remove hydrogen infused during plating and certain other chemical processing such as stripping, chemical milling, pickling, and etching.
Standard

Automated Gaseous Nitrocarburizing Controlled by Potentials

2018-07-02
CURRENT
AMS2759/12B
This specification covers the requirements for producing a continuous white layer with controlled extent of porosity by means of a gaseous process, automatically controlled to maintain set values of the nitriding and carburizing potentials that determine properties of the nitrocarburized surface. Automatic control is intended to ensure repeatability of nitrogen and carbon content of the white layer which influences properties such as wear and corrosion resistance, ductility and fatigue strength.

Gaseous Nitrocarburizing

2018-06-11
CURRENT
AMS2759/13
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 carbon enriched nitriding process. The process is intended to utilize an atmosphere of high nitriding potential that produces a compound layer. If the compound layer is intended to be controlled automatically, AMS2759/12 shall be used.

Gas Nitriding of Low-Alloy Steel Parts

2018-06-11
CURRENT
AMS2759/6C
This document specifies the procedure and requirements for gas nitriding low-alloy and tool steels by the use of raw or dissociated ammonia. Additional alloys and steel families (e.g., stainless steels) can also be nitrided using parameters acceptable to the cognizant engineering organization.
