The
5、 original issue of AMS-H-81200 was taken directly from Military Specification MIL-H-81200A and contained only minor editorial and format changes required to bring it into conformance with the publishing requirements of SAE technical standards. This revision B changes the heat treatment requirements
6、for parts from “may be heat treated in accordance with the requirements of AMS 2801” to “shall be heat treated in accordance with AMS 2801”. As an exception, it allows continuation of heat treatment procedures for specific parts which have been previously acceptable to the purchaser. It also adds th
7、e requirement that the heat treat parameters used for heat-treat-response-tests of raw material conform to the parameters used for heat treatment of parts (See 3.1.1). The original Military Specification was adopted as an SAE standard under the provisions of the SAE Technical Standards Board (TSB) R
8、ules and Regulations (TSB 001) pertaining to accelerated adoption of government specifications and standards. TSB rules provide for (a) the publication of portions of unrevised government specifications and standards without consensus voting at the SAE Committee level, and (b) the use of the existin

Under Department of Defense policies and procedures, any qualification requirements and associated qualified products lists are mandatory for DOD contracts. Any requirement relating to qualified products lists (QPLs) has not been adopted by SAE and is n

AMS-H-81200ASAEAMS-H-81200A - 2 - 1.SCOPE: 1.1Purpose: This specification covers the heat treatment of titanium and titanium alloy mill products (raw material), including wrought and cast products, by material producers. This specification also covers furnace
11、equipment requirements, test procedures, and general information for heat treating procedures, heat treating temperatures, and material test procedures for the heat treatment of titanium and titanium alloys. It also describes procedures which, when followed, have produced the desired properties with

13、i40, Ti55, and Ti70), the following titanium alloys are covered by this specification: 2.APPLICABLE DOCUMENTS: The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent rev
14、ision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply.
