1. SCOPE:

1.1 Scope:

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. This specification is applicable only to the heat treatment of raw material (see 6.1.1); it does not cover the requirements for the heat treatment of steel parts (see 3.4 and 6.1.2). 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.

1.1.1 Limitations: Unless otherwise specified, this specification is not applicable to heating or to intermediate (non-final) heat treatment, of raw material, e.g. for hot working. Processes not covered include deliberate surface heat-treating and specialized heat-treating, such as induction hardening, flame hardening, carburizing, nitriding; however, this specification may be referenced for equipment and controls. Austempering, ausbay quenching and martempering may be used when specified by the cognizant engineering organization.

1.2 Classification:

Steels covered by this specification are classified into the following four classes. Unless otherwise specified, the process and equipment requirements in this specification refer to all classes of steel tabulated in Tables IA, IB, IC and ID, respectively.

Class A - Carbon and low alloy steel

Class B - Martensitic corrosion-resistant steel

Class C - Austenitic corrosion-resistant steel

Class D - Precipitation-hardening and maraging steel
