Scope

Form This specification establishes requirements for steel forgings of any shape or form that finished parts are to be made (See 8.4@ 8.5@ 8.8.4 and 8.10). Application Forgings are typically intended to be manufactured from consumable electrode vacuum remelted steel for use in those high performance parts where control of short transverse tensile properties or fracture toughness is important. The forgings are to be manufactured in accordance with a documented process; product approval is based on first article demonstrations of tensile properties (short transverse if section size allows) and of fracture toughness@ in the section size of the finished part. Certain design and processing procedures may cause some of these products to become susceptible to stress corrosion cracking after heat treatment; ARP1110 recommends practices to minimize such conditions. Classification Forgings shall be of the following grades as specified in the ordering data (See 8.10). When grade is not specified@ Grade A shall apply. Grade A Acceptance tests include verification of room temperature tensile properties and@ when specified@ of room temperature fracture toughness. Preproduction testing includes verification of all requirements; product approval is in accordance with AMS2376. Grade B Acceptance tests do not include verification of mechanical properties. Preproduction testing includes verification of all requirements; purchaser must approve the supplier's process control documentation and the product prior to acceptance of production forgings.
