(OP)
Hi Everyone
In my recent job, I was asked to specify low temperature carbon steel (LTCS MDMT goes down to -48 deg C) in a 150# CS (MDMT to -29) line class to avoid impact test when the wall pipe ecceeds 0.5". I am just wondering which of the A 671 CC60 Vs A 672 C60 grades would fit the purpose ? When I read both specifications they look almost similar ! I would appreciate to share someone else experience in that subject.

* in B31.3 Table 323.2.2A A 671 CC60 and A 672 C60 follow curve C

Regards

The clue might be in the titles of the standards.
