Purpose:

This specification covers the engineering requirements for heat treatment by part fabricators (users) or their vendors or subcontractors, of parts (See 1.1.2) made from the following titanium alloys:

Other Alloys and Heat Treatments: This specification may be used for heat treatment of parts made from alloys other than the above, provided temperatures, times, and quenchants are specified by the cognizant engineering organization. It is permissible, for specific parts, to use equipment, practices, and test methods which conformed to AMS-H-81200 or MIL-H-81200 and were previously acceptable to the purchaser.

Parts: Finished and semi-finished parts, including raw material, heat treated by the parts fabricators, or their vendors or subcontractors, during the fabrication process. (See 8.2.2.)

Qualification of Raw Material:

The temperature, soaking time, and cooling rate requirements specified herein are applicable to testing of raw material by material producers, warehouses/distributors, and forge shops for capability to respond to heat treatment when some or all of these requirements are not included in the procurement specification.

Raw Material:

Heat treatment by material producers, forge shops, and warehouses/distributors, or their vendors, of products listed below should be performed in accordance with the procurement specification. (See 8.2.1.)

Sheet, Plate, Foil, Bar, Rod, Wire, Tubing, Extruded Shapes, Forgings, and Castings.
