NEED ADVICE, PLEASE:

BACKGROUND: Low temperature carbon steel castings LCB and LCC acc. to ASTM A 352 are typically supplied in the “quenched and tempered” heat treatment condition in order to meet the impact test requirements at-46°C. However “quenched and tempered” is not one of the above mentioned acceptable heat treatments acc. to ANSI/NACE MR0175/ISO 15156-2:2015. Acceptable heat treatments that include quenched and tempered also include austenitized, which is not suitable for LCB/LCC.

Question: May LCB and LCC acc. to ASTM A 352 in the quenched and tempered condition be used in applications acc. to ANSI/NACE MR0175/ISO 15156-2:2015, provided that all other requirements acc. to ANSI/NACE MR0175/ISO 15156-2:2015 are met? The same question applies to ANSI/NACE MR0103/ISO 17495:2015, where the same heat treatment requirements are defined in section 13.1.1 Requirements for all carbon and alloy steels.

Thank you in advance for your assistance and advice.
