1 API WI 2366 Ballot Proposal Add Age Hardened Nickel-based New Group 5 to API 5CRA for Coupling Stock and Accessory Material June 2013

2 API WI-2366 NWI proposed API Summer Standards Conference June 2010 to add a new Group 5 to API 5CRA for: – Age hardened nickel based alloys for coupling stock and accessory material. Alloys Include UNS Numbers: N09925, N09935, N09945, N07718, N07716, N For harmonization, WI-2366 coordinated and held alternate meetings with the API 6A718 WG to coordinate development of material requirements for age hardened nickel-based alloys.

3 50 PARTICIPANTS USERS – BP, Chevron, ExxonMobil, Hess, Petrobras, Shell, Statoil & Total. OEMs- BakerHughes, FMC, GE Oil & Gas, Halliburton, Schlumberger, V&M Tube Alloy & Weatherford. MILLS- ATI, Bohler, Carpenter, Foroni, Nippon Steel & Sumitomo Metal, Outokumpu VDM, Salzgitter Mannesmann, & Special Metals. DISTRIBUTORS- Castle Metals, CRA, Energy Alloys, Howco Metals & National Specialty Alloys.

4 SIGNIFICANT COMPLETED ACTIONS Melting Method and Chemistry: – Agreed on primary and secondary melt methods. – Chemistry requirements agreed to suppress formation of secondary phases. Heat Treatment: – Agreement on heat treatment requirements – Monitoring by heat sinks or contact thermocouples. Microstructure: – Agreement on acceptance criteria regarding secondary phases and continuous grain boundary networks. – Standardization of etchants. – Consensus on inclusion of informative reference photomicrographs.

5 SIGNIFICANT COMPLETED ACTIONS Macrostructure: – Agreed acceptance criteria. – Standardization of etchants. Mechanical Properties: – Developed acceptance criteria. – Standardized on transverse Charpy V-Notch (when size permits). – Developed cross-sectional hardness test hardness requirements.

6 SIGNIFICANT COMPLETED ACTIONS NDT: – Consensus for secondary eddy current acceptance criteria. – Agreement for a new eddy current NDT procedure for examining of bar surface using eddy current. It is proposed to include this new procedure in an Annex. – API SC5 RGNDT contributed. Re-testing: Developed requirements for all test methods.

7 Propose Draft Ballot Request permission to move forward to submit proposal for draft ballot to API.
