What is NACE RP0472?

• Sulfide Stress Cracking (SSC): Cracking of a metal under the combined action of tensile stress and corrosion in the presence of water and hydrogen sulfide (H₂S).
• Hydrogen-Induced Cracking (HIC): Cracking resulting from atomic hydrogen diffusing into the steel and combining to form molecular hydrogen at trap sites.
• Hard Spots: Localized areas in the weld or Heat Affected Zone (HAZ) with significantly higher hardness than the surrounding material, making them susceptible to cracking.
