CSOEM Temperature De-Rated Mechanical Properties for HPHT Materials Mechanical data for use with FEA Follow-up to AWHEM on Ni alloy 718 Led by Baker Hughes – active Development Of New Hardness Conversion Tables For ASTM E140 Hardness testing of PH nickel alloys for API 6A718 Hardness testing of martensitic stainless for API 6A Led by Tim Haeberle (GE) – active

CSOEM Task Group on ASTM Material Specifications for Oil and Gas Applications Develop a material specifications for low alloy steel forgings, forged bar and rolled bar used in oil and gas applications Grades covered: F22, 4130 Modified, 8630 Modified Led by Lester Burgess (Texas Screw Products) NDE Requirements for Bar & Tube Missing or varying requirements to be standardized, including test methods Led by John Elwell (HOWCO)

CSOEM API 6A 21st Ed. & NACE MR0175 Materials Issues 6A - Elimination Of Austenitic Stainless Steels Ring Groove Overlays 6A - Addition of Alloy 625 Overlay Minimum Thickness Requirements 6A - Alloy 625 Overlay Composition Requirements MR CRA Overlay Composition Requirements Led by Tim Haeberle (GE) Grade 660 Elevated Temp Tensile Testing Unrealistic derating values in API 6A Appendix G and API TR6MET for ASTM A453 Grade 660 (A286) stainless steels Stronger material at higher temps Grade 660 derating values were removed from Appendix G in API 6A Errata 6 Led by Tim Haeberle (GE) – active

CSOEM API Bolting Specification Needs In response to BSEE, API is implementing new bolting spec requirements The objective is to prevent H-embrittlement failures in marine environments The issue is being addressed somewhat independently in each of the API SC’s Led by Tim Haeberle (GE) OCTG Near-Yield Cyclic Response Assess impacts of near-yield cyclic loading on subsequent response of selected P110 OCTG material Potential for strength reduction has been considered relevant for further optimization of test procedures recommended by API 5C5/ISO Led by Garret Meijer (Noetic Engineering Inc.)

API SC20 Supply Chain Management Chaired by Jerry Longmire Possible Future Standards Heat Treatment in continuous furnaces Metallic plating supplier qualification
