This article provides an in-depth overview of the standard, its evolution, and the crucial guidelines it offers for managing weldment integrity in wet hydrogen sulfide ( H2Scap H sub 2 cap S ) service. 1. What is NACE RP0472 / SP0472?
A central tenet of the standard is that hard microstructures (like martensite) are significantly more susceptible to hydrogen embrittlement. To mitigate this risk, the standard mandates strict hardness limits:
The mandates apply broadly to critical industrial welding processes: : Shielded Metal Arc Welding GMAW : Gas Metal Arc Welding FCAW : Flux-Cored Arc Welding GTAW : Gas Tungsten Arc Welding SAW : Submerged Arc Welding Dual Classification of Cracking Mechanisms nace rp0472 pdf new
Ensures compliance with updated ASME and API codes, which often reference the latest NACE standards.
A genuine new AMPP PDF has:
While many professionals still refer to it as NACE RP0472 , the standard has been updated and re-designated by NACE International (now AMPP) as NACE SP0472 (e.g., SP0472-2010, SP0472-2020). 2. Key Aspects of the NACE RP0472/SP0472 Standard : Specifically covers P-No
It is mandatory for managing environmental cracking in P-No. 1 carbon steels in sour service. is the core strategy.
(formerly RP0472 ), titled "Methods and Controls to Prevent In-Service Environmental Cracking of Carbon Steel Weldments in Corrosive Petroleum Refining Environments," is a critical standard used to ensure the integrity of refinery equipment.

If you are looking for the latest requirements to prevent environmental cracking in carbon steel weldments, do not use NACE RP0472 . You must use AMPP SP0472-2023 .
Cracking caused by specific refinery environments like amine or caustic services. 2. The Role of Hardness Control
