5、008-12 Reaffirmed 2014-06 Superseding AMS5524K Steel, Corrosion and Heat-Resistant, Sheet, Strip and Plate 18Cr - 13Ni - 2.5Mo (SAE 30316) Solution Heat Treated (Composition similar to UNS S31600) RATIONALE This document has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE 1.
6、1 Form This specification covers a corrosion and heat-resistant steel in the form of sheet, strip, and plate. 1.2 Application These products have been used typically for parts requiring both corrosion and heat resistance up to 1600 F (871 C), but usage is not limited to such applications. At elevate
7、d temperatures, strength of this steel is slightly higher than, and oxidation resistance is similar to that of 18-8 type steels. 1.2.1 Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP1110 recommends practices to minimize such c
8、onditions. 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 document unless a specific document issue is specified. When the
9、referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply.
