Purpose This specification specifies the engineering requirements for heat treatment@ by part fabricators (users) or their vendors or subcontractors@ of parts made of wrought nickel or cobalt alloys@ of raw materials during fabrication@ and of fabricated assemblies in which wrought nickel or cobalt alloys are the primary structural components. Application Alloys Detailed heat treating instructions are specified for the age-hardenable (precipitation-hardenable) and non-agehardenable alloys listed in 8.2. However@ this specification also may be used for alloys other than those listed in 8.2 provided that temperatures@ soaking times@ and cooling requirements are specified by the cognizant engineering organization. Heat Treatments Heat treatments covered by this specification are as follows: Solution Treating (See 8.4.7) Annealing (See 8.4.8) Stabilization Annealing (See 8.4.10) Interstage Annealing (See 8.4.13) Stabilization (See 8.4.11) Precipitation (See 8.4.12) Equalization (See 8.4.14) Stress Relief (See 8.4.9). Safety - Hazardous Materials While the materials@ methods@ applications@ and processes described or referenced in this specification may involve the use of hazardous materials@ this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
