10423:2009 / API 6A 20th ed.

Table 9 – Steel composition limits

slide3

API 6A 20th edition deleted limit on Nickel.

  • Reasons for change:
    • Nickel limit is not required for non-NACE equipment (Matls Class AA, BB, CC).
    • Deleting limit on Ni allows use of additional material grades such as 4340 for AA-CC.
    • Deleting limit on Ni allows use of full ASTM chemistry range of currently-used materials such as F6NM.
slide4

API 6A 20th edition deleted limit on Nickel.

  • Concerns about this change:
    • Users of undocumented equipment cannot base acceptance for sour service on hardness alone.
    • Practice of using hardness testing as basis of conformance to NACE MR0175 is prevalent.
    • Limits interchangeability of equipment.
    • Limits flexibility of repaired and remanufactured equipment. (Not addressed in Annex J)
slide5

API 6A 20th edition deleted limit on Nickel.

  • Questions about this change:
    • Is the benefit of using 4340 or unrestricted F6NM significant relative to the increased risk?
    • Are there other alloys/material grades that would also be used as a result of this change?
    • Should the change be addressed in Annex J?
    • Does this affect other product specifications that reference 6A/10423?
slide6

Proposed new work item:

  • Convene a new task group or ask Materials Task Group to consider the effects of this change from 6A 15th – 19th editions, and make a recommendation to keep or reverse it.
