3.7035 – R50400
Material search
Material description
The material 3.7035 is an unalloyed pure titanium that belongs to the group of reactive metals. It is characterised by high corrosion resistance, which is caused by a dense and firmly adhering oxide layer. If this layer is damaged, oxygen causes new oxide to form.
Titanium Grade 2 is stable in:
- Brackish and sea water
- chlorine oxide
- hypochlorites
- hypochlorates
- humid chlorine gas
- sulphides
- nitric acid
- low-melting metals
Titanium grade 2 also offers good mechanical properties with a low specific weight. In addition to the favourable density/strength ratio, the material has high ductility and good creep strength.
AN OVERVIEW OF THE PROPERTIES OF 3.7035:
- Good mechanical properties
- Good notched impact strength
- Very good elongation and strength ratio
- Very good oxidation resistance in reduced and strongly oxidising media
- Good resistance to salt water
Applications
- Heat exchanger components for use with seawater and brackish water
- Electroplating
- Components in flue gas desulphurisation systems
- Medical technology
- Aerospace industry
- Motorsport
- Sports and leisure industry (e.g. boat accessories, bicycle construction, mountaineering equipment, etc.)
