|---|---|---|---|---|---|---|---|
| Titanium has useful corrosion resistance in dilute hydrochloric acid applications. Small amounts of multivalent metal ions in solution can effectively inhibit corrosion. | |||||||
| Sulfuric Acid | |||||||
| Titanium is corrosion resistant to sulfuric acid only at low temperatures and concentrations such as 20% acid at 32ºF and 5% acid at room temperature. Like hydrochloric acid, small amounts of multivalent metal ions in solution can effectively inhibit corrosion as illustrated below. | |||||||
| Titanium Grade 2 Corrosion Resistance to H2SO4 | |||||||
| Concentration (%) | Inhibitor Added | Temp. (ºF) | Corrosion (mpy) | ||||
| 20 | None | 210 | > 2400 | ||||
| 20 | 2.5 g/l Copper Sulfate | 210 | < 2 | ||||
| 20 | 16 g/l Ferric Ion | Boiling | 5 | ||||
| Organic Acids | |||||||
| Unalloyed titanium generally has
good resistance many organic acids.
