Grade 1 titanium welded tube for Heat exchangers

Titanium Grade 1 – Grade 1 is the softest titanium alloy, known for exceptional corrosion resistance, high ductility and very low weight. It is a material often used in the chemical process industry, marine engineering, medicine and heat exchangers. The alloy is commercially pure titanium with over 99.5% purity and is characterized by very good formability, weldability and biocompatibility.

Type: Unalloyed, commercially pure titanium (minimum 99.5% Ti)
Structure: HCP structure (hexagonal close-packed)
Developed for: Applications with requirements for corrosion resistance and biocompatibility
Alternative names: Titanium Grade 1, CP Titanium Grade 1, UNS R50250, ASTM B265, Werkstoffnr 3.7025

Exceptional corrosion resistance in oxidizing and chloride environments
Very low weight (approx. 45% lighter than steel)
Extremely good formability and weldability
Biocompatible – used in implants and medical technology
Good toughness even at very low temperatures

Low strength compared to other titanium alloys (e.g. Grade 5)
Not hardenable by heat treatment
Not optimal for heavy loads or high temperatures (>300°C)

Chemical industry: Equipment in chloride environments – acid resistant + low weight
Medicine / Biotechnology: Implants, orthopedic devices – biocompatibility
Marine technology: Boat components, heat exchangers – seawater resistance
Paper & pulp: Bleaching systems, pipes – acid resistance
Heat exchangers / Energy: Pipes and plates in corrosive systems – low weight, high resistance

Passive oxide film provides extremely good protection in oxidizing environments
Resistant to chlorides, acids and seawater
Not susceptible to stress corrosion cracking in most liquids
 

Hot and cold seawater
Chloride solutions (e.g. NaCl, CaCl₂)
Oxidizing acids (nitric acid, chromic acid)
Organic acids, alkaline solutions, hydrogen peroxide
 

Hydrofluoric acid (HF)
Reducing acids (hydrochloric acid, sulfuric acid at high temperatures)
Environments with high concentration of metal chlorides at high temperatures

Property (Typical value)
Yield strength (0.2%): ~170–240 MPa
Tensile strength: ~240–350 MPa
Elongation at break: ~24–30%
Density: ~4.51 g/cm³
Elastic modulus: ~105 GPa
Thermal conductivity: ~17 W/m·K
Application temperature: Rec. ≤ 300°C (briefly up to 425°C)
Weldability: Excellent – low risk of cracking
Machinability: Very good – especially in annealed condition
