There are 7 grades of Titanium: Grade 1, Grade 2, Grade 3, Grade 4, Grade 7, Grade 9, and Grade 12. We normally used Grade 1, 2, and 7 produce Spiral Wound Gaskets.

Corrosion Resistance:
Titanium is by nature, a reactive metal. It is protected by a titanium dioxide surface film with high thermodynamic stability in many corrosives such as natural waters, oxidizing acidic brines and many other environments.
