Nace Rp0472 Pdf -

NACE RP0472, redesignated as NACE SP0472 and currently in its 2020 version, establishes essential guidelines for controlling carbon steel weldment hardness to prevent environmental cracking in petroleum refining environments. The standard dictates specific practices, such as a 200 Brinell hardness limit, to prevent cracking mechanisms like sulfide stress cracking and alkaline stress corrosion cracking.

Microhardness testing (typically Vickers HV5 or HV10) is performed across a cross-section of the test weld, targetting the weld metal, the fusion line, and various zones within the HAZ. 3. Production Weld Testing
