Transcript API 6A718 Work Group on Addition of Nickel Base CRAs Paul Maxwell

API 6A718 Work Group on
Addition of Nickel Base CRAs
API SC6 Summer 2012 Meeting
Paul Maxwell
Objective
• Provide requirements for Age Hardened Nickel
Base alloys used in the manufacture of API 6A
pressure-containing and pressure-controlling
components to assure they are not embrittled by
the presence of an excessive level of deleterious
phases and meet minimum metallurgical quality
requirements.
• These additional requirements include detailed
process control requirements and detailed
testing requirements.
