Form

This specification establishes requirements for titanium forgings of any shape or form from which finished parts are to be made. (See 8.3, 8.5.4, and 8.7).

Application

These forgings are used typically in the manufacture of high-performance parts when control of short-transverse tensile, fracture toughness, tensile creep, or tensile rupture is required, but usage is not limited to such applications.

These forgings are to be manufactured in accordance with a documented process; product approval is based on first-article demonstrations of mechanical and microstructural properties in the heat-treat condition and section size of the finished part.

Certain design and processing procedures may cause some of these products to become susceptible to stresscorrosion cracking after heat treatment; ARP982 recommends practices to minimize such conditions.

Classification

Forgings shall be of the following Grades as specified in the ordering data. (See 8.4). When no Grade is specified, Grade A shall apply.

Grade A

Acceptance tests include verification of room-temperature tensile properties and, when applicable, of room-temperature fracture toughness. Preproduction testing includes verification of all applicable requirements.

Grade B

Acceptance tests do not include verification of mechanical properties. Preproduction testing includes verification of all applicable requirements.
