5、 These castings have been used typically for parts requiring good corrosion resistance and strength up to 600 F (316 C), but usage is not limited to such applications (See 8.3). 1.2.1Certain processing procedures and service conditions may cause these castings to become subject to stress-corrosion c
6、racking; ARP1110 recommends practices to minimize such conditions. Where stress-corrosion is considered to be a factor, precipitation 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
7、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.
