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

Rotary Flap Peening of Metal Parts

2018-10-17
WIP
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.

Vacuum Gauge Calibration

2018-09-26
WIP
B18AA
This SAE Aerospace Recommended Practice (ARP) addresses the general procedure for the best practices for minimizing uncertainty when calibrating thermal conductivity and cold cathode vacuum gauges, which includes the vacuum sensor(s) and accompanying electronics necessary for a pressure measurement to be made. It also includes the best practices for an in-process verification where limitations make it impossible to follow the best practices for minimizing uncertainty.
Standard

Flux, Aluminum Welding

2018-09-20
WIP
AMS3414F
This specification covers an aluminum welding flux in the form of powder.
Standard

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.
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.
Standard

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

Carburizing and Heat Treatment of Carburizing Grade Steel Parts

2018-08-14
WIP
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

Plating, Silver Nickel Strike, High Bake

2018-07-27
CURRENT
AMS2410L
This specification covers the requirements for electrodeposited silver on other metals, usually with a nickel strike between the basis metal and the silver.
