Titanium Grade 2 – properties, applications and technical data
Titanium Grade 2 (GR2, UNS R50400, W.Nr. 3.7035) is a filler material for welding commercially pure titanium. The material is used in applications where low weight, very good corrosion resistance and good mechanical strength are crucial.
This welding material is particularly suitable for structures in marine environments, chemical process industries and medical technology applications where high reliability and long service life are required.
Properties of Titanium Grade 2
Titanium Grade 2 is a commercially pure titanium material with very good corrosion resistance in a wide range of aggressive environments. The weld metal deposited with this material exhibits good toughness, good formability and stable mechanical properties.
The material is also biocompatible, making it suitable for welding medical components and implants.
