7、F (316 C), but usage is not limited to such applications. 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 conditions. 1.3 Classification Product covered by this specification is
8、classified as follows: Type 1 - Steel multiple melted using vacuum consumable electrode practice during remelting Type 2 - Steel multiple melted using electroslag process in the final melting cycle 1.3.1 Unless a specific type is ordered, either type may be supplied. 2. APPLICABLE DOCUMENTS The issu
9、e 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 referenced document has been cancelled and
10、no superseding document has been specified, the last published issue of that document shall apply.
