Applied range of different grade titanium:
Titanium in grade 1 and 2 is used in the chemical industry and marine technology because of its resistance to corrosion.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.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. In addition, Titanium Grade 7 is resistant to erosion or impacts.
Titanium Grade 12 alloy is similar to Titanium Grades 2 and 3 except that Titanium Grade 12 has 0.3% molybdenum and 0.8% nickel. This offers enhanced corrosion resistance.
Gr16 Medium-strength titanium plus 0.04-0.08% Pd for enhanced corrosion properties Titanium tube grades (other grades are available on request).
