| PREN (Pitting Resistance) | ~24–26 | ~34–43 |
| Sulfuric Acid Resistance | Limited to low concentrations | Excellent (up to 35°C) |
| Stress Corrosion Cracking | Susceptible | Highly Resistant |
| Common Use | Food, Architectural, General Marine | Chemical Processing, Oil & Gas, Desalination |
Strategic Applications: Where 904L Plates Excel
Chemical Processing: Used in scrubbers, tanks, and heat exchangers handling dilute sulfuric and acetic acids.
Seawater Cooling Systems: 904L provides the necessary protection against chloride pitting in desalination plants and offshore oil platforms.
Pharmaceutical Production: Where purity and the prevention of metal contamination are paramount, the stability of 904L is unmatched.
Pulp and Paper: Specifically in bleach plant equipment where corrosive chemicals are used at elevated temperatures.
