5、seding AMS5630K Steel, Corrosion-Resistant, Bars, Wire, and Forgings 17Cr - 0.52Mo (0.95 - 1.20C) (440C) (Composition similar to UNS S44004) RATIONALE AMS5630L removes the requirements for microinclusion rating, grain size, and conformance to AMS2303 introduced at revision K. This results in changes
6、 to Acceptance Tests (4.2.1) and Reports (4.4). 1. SCOPE 1.1 Form This specification covers a corrosion-resistant steel in the form of bars, wire, forgings, and forging stock. 1.2 Application These products have been used typically for parts requiring hardness up to 58 HRC and resistance to wear, co
7、rrosion, and oxidation, but usage is not limited to such applications. 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 of a docum
8、ent 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.
