MIL-H-6875H, MILITARY SPECIFICATION HEAT TREATMENT OF STEEL, PROCESS FOR (1 MAR 1989) [S/S BY SAE-AMS-H-6875]., This spec!flcatlon covers the requirements for heat-treatment offour classes of steel (see 1.2) and the requirements for furnace equipment, testprocedures and information for heat-treating procedures, heat-treatingtemperatures and material (see 6.11) test procedures. It is applicable to allheat treatment of parts and to only the heat treatment of mill products whichcould affect Its fabricab!l!ty or the properties of parts. This specificationalso describes procedures which, when followed, wI1l produce the desiredproperties and material qualitles within the limitations of the respectivealloys tabulated In Tables IA, IB, IC and ID. A11OYS other than thosespecifically covered herein may be heat treated using all applicablerequirements of this specification.
