The Corrosion Resistance Of Industrial Pure Titanium Under Different Compounds
Mar 20, 2026
The corrosion resistance of titanium is classified into three grades:
Excellent - highly resistant to corrosion, with a corrosion rate of less than 0.127 mm per year
Good - moderately resistant to corrosion, with a corrosion rate ranging from 0.127 to 1.27 mm per year
Poor - not resistant to corrosion, with a corrosion rate of more than 1.27 mm per year
