What is NACE MR0175 criteria for HIC retesting? NACE MR0175 Part 2 Clause B.2.2 provides clear guidance on SSC/HIC/SOHIC/SZC retesting as follows: If a single specimen fails to satisfy the acceptance criteria, the cause shall be investigated. If the source material conforms to the manufacturing specification, two further specimens may be tested. These shall be […]
QUESTION: ISO 15156-2 Annex A.2.1.4 differentiate between “carbon steel”, “carbon manganese steel” and “low-alloy steel”. The terms “carbon steel” and “low-alloy steel” are defined in ISO 15156-1, but not “carbon manganese steel”. What is the definition of “carbon manganese steel” in the scope of NACE MR0175? (MP INQUIRY #2017-23) ANSWER: Although not directly defined in […]
