Guidance on which materials (e.g., carbon steel, stainless steel, alloys) are suitable for concentrated H₂SO₄.

For anyone working in Chemical Process Industries (CPI) or mineral processing, this document is not just a reference—it is a safety requirement for preventing hazardous leaks and ensuring operational longevity. NACE Standard RP0391-2001 - ANSI Webstore nace rp 0391 pdf

NACE RP0391 is essential for chemical engineers, storage facility operators, and corrosion specialists. By strictly adhering to the material selection, temperature limits, and contamination control measures detailed in this standard, organizations can maximize the life of their infrastructure and ensure safety in sulfuric acid handling. To get the most accurate and safe design, you may want to:

The standard discusses when liners are necessary. Fe+H2SO4→FeSO4↓+H2↑Fe plus H sub 2 SO sub 4

When concentrated sulfuric acid (90% to 100% concentration) first touches a carbon steel tank, a violent reaction seems imminent. However, something remarkable happens: the acid immediately attacks the steel to form ferrous ions hydrogen gas . These ions quickly create a thin, protective layer of Iron Sulfate ( cap F e cap S cap O sub 4 on the surface. ScienceDirect.com

Generally addresses different aspects of corrosion control. Materials Other Than Steel: For temperatures above By strictly adhering to the material selection, temperature

If you are dealing with a specific material issue, let me know: Are you dealing with sulfuric acid concentration below 90%?

Metadata covering metals, alloys, and reactive limits.

Disclaimer: Ensure you are obtaining the updated version, as NACE RP0391 was revised to SP0391 in 2001 1.2.4. Conclusion

In practice, deepwater engineers use standards in tandem to specify materials that are resistant to internal reservoir fluids (MR0175) and external subsea environments (RP0391). How to Access the NACE RP0391 PDF Legally
