I confess I've never heard the term CET. The MDMT pertains to resistance to brittle fracture in carbon and low alloy steel. The MDMT is used to determine the need for Charpy impact testing. Just guessing, but I daresay the the CET is some sort of upper temperature limit relating to creep or metallurgical effect. The MDMT reflects a limit on low temperature service.
