6、 to comply with the SAE five-year review policy. 1. SCOPE 1.1 Form This specification covers a corrosion resistant steel in the form of investment castings. 1.2 Application These castings have been used typically for parts requiring good corrosion resistance and strength up to 600 F (316 C), but usa
7、ge is not limited to such applications (See 8.3). 1.2.1 Certain processing procedures and service conditions may cause these castings to become subject to stress-corrosion cracking; ARP1110 recommends practices to minimize such conditions. Where stress-corrosion is considered to be a factor, precipi
8、tation heat treatment should be performed at a temperature not lower than 1000 F (538 C). 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
9、revision 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,
