321 Stainless Steel Corrosion Resistance Performance

1. Can 321 resist intergranular corrosion? Yes, titanium stabilization prevents this issue even after welding.

2. Is 321 suitable for seawater applications? No, it lacks molybdenum and is prone to pitting corrosion in saltwater.

3. How does 321 perform in nitric acid? It has excellent resistance to dilute and concentrated nitric acid at moderate temperatures.

4. Can 321 be used in sulfur-containing environments? It resists mild sulfidation but should be avoided in high-sulfur (>0.1%) atmospheres.

5. What is the best environment for 321? Welded structures, high-temperature oxidizing environments, and nitric acid processing.
