Resistant to strong acid and corrosion GR12 titanium bar
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.

Typical applications
1.Refinery desulphurisation unit:
->Replaced original 316L stainless steel, extended service intervals from 6 months to 5 years.
2.Printed circuit board plating equipment:
->heater tube life extended from 1 year (titanium-palladium alloy) to 8 years, cost reduction of 60%.
3.Geothermal power generation system:
->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.
