标准摘要
This document provides requirements for Nickel Base Alloy 718 (UNS N07718) that are intended to supplement the existing requirements of API Spec 6A and ISO 10423. These additional requirements include detailed process control requirements and detailed testing requirements. The purpose of these additional requirements is to ensure that the Nickel Base Alloy 718 used in the manufacture of API Spec 6A or ISO 10423 pressure-containing and pressure-controlling components is not embrittled by the presence of an excessive level of deleterious phases. This standard is intended to apply to pressure containing and pressure controlling components covered by API Spec 6A and ISO 10423, but is not invoked by API Spec 6A and ISO 10423. This standard is applicable when invoked by the equipment manufacturer or the equipment purchaser.
