GR12 Titanium Bar Rod - Corrosion-Resistant, High-Strength, China Suppliers & Factory, ASTM B348, Φ5-100mm
Products Details
GR12 titanium alloy (Ti-0.3Mo-0.8Ni) is a high performance material designed for extreme corrosive environments. Its core strength lies in its excellent resistance to reducing acids such as hydrochloric acid, sulphuric acid and stress corrosion cracking, as well as good cold workability and weldability.

Advantages and Application
Extreme corrosion resistance: perfect for reducing acid environments
| Corrosive environments | GR12 Performance (annual corrosion rate) | Comparative materials (GR5/316L stainless steel) |
|---|---|---|
| Boiled hydrochloric acid (20%) | <0.1 mm/y | GR5: >1.2 mm/y, 316L: perforated |
| High temperature sulfuric acid (50°C) | 0.05 mm/y | GR2: 0.5 mm/y |
| Wet hydrogen sulfide with Cl | Zero-stress corrosion cracking | 316L: Cracking within 3 months |
Typical applications
Replaced original 316L stainless steel, extended service intervals from 6 months to 5 years.
Heater tube life extended from 1 year (titanium-palladium alloy) to 8 years, cost reduction of 60%.
10 years continuous operation without corrosion in pH=2 geothermal fluid.
GR12 Titanium alloy rod is mainly used in the chemical industry, such as, acid pipelines, electrolysis tanks, petroleum refining desulphurisation equipment, electroplating industry in the use of heating pipes and geothermal energy systems. In high temperature, high corrosive media life of up to 5-10 times that of ordinary stainless steel, is a cost effective alternative to Hastelloy and Tantalum solutions.
We are committed to providing our customers with high quality Industrial GR12 Titanium Rod products and professional services and look forward to recommending the most suitable grades and specifications for your projects and working with you to reduce costs and increase efficiency.

Frequently Asked Questions
What is GR12 titanium alloy?
GR12 titanium alloy (Ti-0.3Mo-0.8Ni) is a high performance material designed for extreme corrosive environments. It features excellent resistance to reducing acids (such as hydrochloric and sulphuric acid) and stress corrosion cracking, along with good cold workability and weldability.
What standard does the GR12 titanium alloy parameter table comply with?
The chemical composition and mechanical properties of our GR12 titanium alloy products comply with the ASTM B348 standard.
How does GR12 compare to 316L stainless steel in boiled hydrochloric acid?
In boiled hydrochloric acid (20%), GR12 has an annual corrosion rate of <0.1 mm/y, whereas 316L stainless steel gets perforated under the same conditions.
What are the typical applications of GR12 titanium alloy rods?
It is primarily used in the chemical industry for acid pipelines, electrolysis tanks, refinery desulphurisation units, heating pipes in the electroplating industry, and geothermal power generation systems.
Why is GR12 titanium alloy considered a cost-effective choice?
In high temperature, high corrosive media, its service life is 5-10 times that of ordinary stainless steel. This makes it a highly cost-effective alternative to expensive Hastelloy and Tantalum solutions.
