AMPP - The Association for Materials Protection and Performance Hardness Limits : Establishes a maximum hardness of 200 Brinell (HBW)
If you are looking for the latest insights regarding the updates, this comprehensive article breaks down the standard's history, its transition from a Recommended Practice (RP) to a Standard Practice (SP), core technical requirements, and best practices for compliance. 1. The Evolution: From NACE RP0472 to SP0472
Hardness in the HAZ is more difficult to measure in the field, so the standard relies on procedural controls rather than just spot testing. Overview of NACE International Standard RP0472

: Verification often occurs during the qualification of welding procedures. Essential variables must be controlled to ensure production welds match the qualified test samples.
The primary goal of NACE SP0472 is to provide methods for producing weldments in P-No. 1 carbon steels that are resistant to in sour and corrosive refinery services. It specifically addresses two main cracking mechanisms:
The standard provides a clearer, non-mandatory Appendix (Appendix A) detailing the technical justification for the hardness limits. AMPP - The Association for Materials Protection and
