High hardness is a primary indicator of susceptibility to cracking. The standard typically mandates a maximum hardness of 200 Brinell (HBW) for the weld deposit. Post-Weld Heat Treatment (PWHT):

By investing in the new PDF and implementing it correctly, you are not just checking a box—you are preventing catastrophic pipe support failures that cost millions in unplanned downtime. Corrosion under pipe supports is a silent threat. NACE RP0472 (new version) is your most effective defense.

Welding procedures must be qualified with hardness testing to ensure the hardness limits are met. nace rp0472 pdf new

For materials engineers, welding inspectors, and asset integrity managers, downloading the official NACE SP0472 PDF via the ANSI Webstore provides the precise technical criteria needed to prevent stress corrosion cracking and hydrogen-induced failures in downstream processing units. Overview and Scope of NACE SP0472

Generally, a maximum hardness limit of 225 HBW or 200 HBW (depending on the specific environment) is recommended to prevent HSC. High hardness is a primary indicator of susceptibility

The standard applies to all P-No. 1 carbon steels (such as A516, A106, A105) often used in refineries. It provides guidance on:

The standard outlines three critical control methods to maintain the integrity of the steel: Hardness Control: Corrosion under pipe supports is a silent threat

The National Association of Corrosion Engineers (NACE) has recently released an updated version of its standard, NACE RP0472, which focuses on the cathodic protection of offshore structures. This article aims to provide an in-depth overview of the updated NACE RP0472 PDF, highlighting its significance, key changes, and best practices for ensuring the integrity of offshore structures.
