6、ear Review and update of this specification. 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 which will be machined in the solution heat treated condition and, after precipit
7、ation heat treatment, will require good corrosion resistance and strength up to 600 F (316 C), but usage 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 recommen
8、ds 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 of the purchase order for
