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.

This document specifies the procedure and requirements for nitriding steel parts in a process automatically controlled by the nitriding potential.

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.

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.

This specification, in conjunction with the general requirements for steel heat treatment in AMS2759, establishes requirements for thermal stress relief treatments of parts manufactured from the following materials:

This specification provides establishes pyrometry exceptions and additions for HIP equipment to those identified in AMS2750.

This specification covers two types of polyalkylene glycol in the form of a liquid.

This specification, in conjunction with AMS2750, covers pyrometric requirements for equipment used for the thermal processing of nonmetallic products. Specifically, it covers temperature sensors, instrumentation, thermal processing equipment, correction factors and instrument offsets, system accuracy tests, and temperature uniformity surveys. These are necessary to ensure that products are cured or formed in accordance with the applicable specification(s). This specification also covers pressure or vacuum requirements for thermal processing equipment.

This specification establishes the engineering requirements for the heat treatment of titanium and titanium alloy mill products (raw material), including wrought and cast products, by material producers and their subcontractors.

An analysis was made of the effects of various surface conditions on the heat up time of steel bars which are heated in atmosphere furnaces to the temperature range used for steel hardening or normalizing. The purpose was to examine whether a standard heating time for a given section thickness is acceptable.

The objective of this program is to compare the properties of aus-bay quenched 300M steel with the properties of 300M steel oil quenched in the conventional manner.

Performed tensile and fatigue tests on bolts to determine if cutting of materials flow lines at the bolt underhead would degrade bolt integrity. Five different alloys used in aerospace industry fatigue critical applications were employed to fabricate 5/16 to 1/2 inch diameter bolts. These bolts were machined from bar stock producing fully cut material flow lines under their heads. Tensile testing with and without underhead washers was performed along with industry standard fatigue testing.

This Aerospace Standard (AS) establishes the requirements for suppliers of Shot Peening Services to be accredited by the National Aerospace and Defense Contractors Accreditation Program (NADCAP). NADCAP accreditation is granted in accordance with SAE AS7003 after demonstration of compliance with the requirements herein. The requirements may be supplemented by additional requirements specified by the NADCAP Nonconventional Machining and Surface Enhancement (NMSE) Task Group. Using the corresponding Audit Criteria (PRI AC7117) will ensure that accredited Shot Peening suppliers meet all of the requirements in this standard and all applicable supplementary standards. The purpose of this audit program is to assess a supplier's ability to consistently provide a product or service that conforms to the technical specifications and customer requirements.
