Titanium corrosion resistance
- Thread starter swgold
- Start date
You should really discuss this with an expert from one of the titanium producers like Timet, RTI, or Wah Chang. ASM Handbook Volume 13 shows the following data for boiling sulfuric acid:
1% concentration has corrosion rate of 17.8 mm/year
5% concentration has corrosion rate of 25.4 mm/year
However, this can be dramatically reduced by having more oxygen present, or by adding small amounts of oxidizing substances like CuSO4. 5% concentration of H2SO4 + 0.25% CuSO4 at 95 C has a corrosion rate listed as nil.
