Nace Rp0472 Pdf |work| -

NACE RP0472 (now updated to NACE SP0472 ) is the essential standard for preventing environmental cracking in carbon steel weldments used in petroleum refining. It specifically targets "P-1" steels (those with a tensile strength ≤ 70,000 psi). The standard focuses on two primary cracking mechanisms: Hydrogen Stress Cracking (HSC): Controlled by limiting the of the weld deposit and the heat-affected zone (HAZ). Alkaline Stress Corrosion Cracking (ASCC): Prevented primarily through Post-Weld Heat Treatment (PWHT) to reduce residual tensile stresses. Key Technical Requirements Hardness Limit: The standard specifies a maximum weld deposit hardness of (Brinell). HAZ Control:
