Key Features
Grade 3 Titanium possesses a combination of material characteristics that make it particularly well suited for chemical processing, marine, electrochemical, and structural applications where strength and corrosion resistance must be combined:
Highest Strength Among Commercially Pure Titanium Grades (450 MPa tensile / 380 MPa yield)
Grade 3 Titanium occupies a critical position between the ductility of lower-strength CP grades and the elevated mechanical performance of alloyed titanium. Its oxygen-controlled interstitial composition drives strength — with 450 MPa tensile strength, 380 MPa yield strength, and 18% elongation — without compromising formability or weldability.
Excellent Corrosion Resistance (Pitting, Crevice & General)
Grade 3 Titanium resists pitting, crevice, and general corrosion in both aqueous and seawater environments. Its naturally forming TiO₂ oxide layer provides durable protection in the aggressive chemical and marine conditions encountered in process vessels, heat exchangers, and piping systems.
Good Weldability
The oxygen-controlled composition maintains full weldability, supporting fabrication of complex assemblies by TIG and other inert-gas shielded methods without post-weld embrittlement or loss of corrosion performance.
Biocompatibility & Non-Magnetic Character
Grade 3 Titanium is bioinert, non-toxic, and non-magnetic, making it a reliable substrate for biomedical research, electrochemical studies, and scientific instrumentation where interference from magnetic materials cannot be tolerated.
Proven Research Substrate (ASTM B265)
Supplied to ASTM B265, Grade 3 foil offers a reproducible, specification-controlled platform particularly valued in electrochemical studies, corrosion testing, and thin-section structural evaluations where a commercially pure titanium substrate with proven mechanical integrity is required.
Industrial Applications
Grade 3 Titanium is used across chemical, marine, biomedical, and research sectors where the highest strength available in a commercially pure titanium grade is required alongside reliable corrosion resistance:
- ✦ Chemical Process Vessels & Piping
- Grade 3 Titanium is used in process vessels, reactors, and corrosion-resistant piping systems where its superior strength over lower CP grades reduces wall thickness requirements while maintaining full resistance to aggressive chemical environments.
- ✦ Heat Exchangers & Marine Structural Components
- Employed in heat exchanger tubing and marine structural parts exposed to seawater, where resistance to pitting and crevice corrosion combined with higher mechanical strength ensures long service life in demanding offshore and coastal environments.
- ✦ Electrochemical & Corrosion Research
- Used as a reproducible, specification-controlled substrate in electrochemical studies and corrosion testing, where its biocompatibility, non-magnetic character, and proven mechanical integrity make it a reliable platform for both laboratory and industrial research programmes.
- ✦ Biomedical & Scientific Instrumentation
- Grade 3 Titanium's bioinert, non-toxic, and non-magnetic properties support its use in thin-section biomedical components and scientific instruments where material interference must be minimised and dimensional stability under load is required.
- ✦ Thin-Section Structural Fabrication
- Supplied to ASTM B265, Grade 3 foil is formed and welded into precision structural components where the strength margin over Grades 1 and 2 allows for thinner, lighter assemblies without sacrificing structural integrity or corrosion performance.
