This specification covers the requirements for heat-treatment of four classes of steel (see 1.2) and the requirements for furnace equipment, test procedures and information for heat-treating procedures, heat-treating temperatures and material (see 6.11) test procedures. It is applicable to all heat treatment of parts and to only the heat treatment of mill products which could affect its fabricability or the properties of parts. This specification also describes procedures which, when followed, will produce the desired properties and material qualities within the limitations of the respective alloys tabulated in Tables IA, IB, IC and ID. Alloys other than those specifically covered herein may be heat treated using all applicable requirements of this specification.
This specification covers the requirements for embrittlement relief (baking) of heat treated steel parts to remove hydrogen infused during plating and other chemical processing (e.g., stripping, chemical milling, pickling, and etching).
This specification covers the engineering requirements for producing a thin epsilon-iron nitride case on parts by means of a low- temperature, aerated, fused salt bath process and the properties of the case.
This AIR presents an abbreviated review of the metallurgical phenomena known as whiskers. It is not all encompassing; rather, it is intended to introduce the design engineer to the technical issues of metallic whiskers, their formation, and the potentially dangerous problems they can cause.
