Feature
Titanium in grades 1 and 2 is used because of its resistance to corrosion in the chemical industry and marine technology. In addition, titanium grade 1/2 is also used in plant engineering, medical technology and in the watch and jewelery industries. Titanium Grade 7 is preferably used in chemical plants. Gr7: Due to the high palladium content, Titanium Grade 7 is very resistant to corrosion. Thus, for example, titanium grade 7 is resistant to salt water and is suitable for handling chlorides media.
