5、Resistant, Bars, Wire, Forgings, Tubing and Rings 16Cr 4.0Ni 0.30Cb (Nb) 4.0Cu Solution and Precipitation Heat Treated (H1150) (Composition similar to UNS S17400) RATIONALE AMS5643/1150 is a new specification for purchase of corrosion-resistant steel product in the solution and precipitation heat tr
6、eated condition. 1. SCOPE 1.1 Form This specification covers a corrosion-resistant steel product in the solution and precipitation heat treated (H1150) condition. 1.1.1 The aged product may be supplied directly by a mill or by a producer other than the mill. The latter would be accomplished by preci
7、pitation heat treatment of solution treated material previously certified to AMS5643. The entity assuming responsibility for the aging operation is designated the producer of AMS5643/H1150. 1.2 Application These products have been used typically for parts requiring corrosion resistance and high stre
8、ngth up to 600 F (316 C) but usage is not limited to such applications (See 8.1). 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 revision
9、 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. 2.1 SAE Publications Available from SAE International, 400 Commonwealth Drive, Warrenda
