[Hajiwaji]

For caustic environment containing H2S and meet the definition of sour as per NACE MR 0103, does require testing and qualification for ssc? N06040 is not listed in NACE MR 0103 section 14.

Check 14.1.1.2 against the base requirements for A494 N06040. Then review clause 11.

Thank you Dr. Jones.

N06040 does not meet the chemical composition requirements in clause 14.1.1.2 of NACE MR 0103, hence qualifications are required as per clause 11.
