    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

    • 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.

    Frequently Asked Questions

    What is GR12 Titanium Alloy?
    GR12 is a high-performance titanium alloy (composed of Ti-0.3Mo-0.8Ni) specifically engineered to offer exceptional strength and resistance in highly corrosive environments, particularly against reducing acids.
    Which standards do your GR12 titanium rods comply with?
    Our GR12 titanium rods and bars are manufactured in strict compliance with the ASTM B348 standard, ensuring premium chemical composition and mechanical properties.
    How does GR12 compare to 316L stainless steel?
    GR12 offers vastly superior corrosion resistance. For example, in boiled hydrochloric acid (20%), GR12 suffers minimal corrosion (<0.1 mm/y) while 316L gets perforated. In wet hydrogen sulfide, GR12 has zero stress corrosion cracking compared to 316L which typically cracks within 3 months.
    What are the primary applications of GR12 titanium alloy?
    It is widely used in chemical acid pipelines, electrolysis tanks, oil refinery desulphurisation units, electroplating heating pipes, and geothermal power generation systems.
    Why is GR12 considered a cost-effective alternative to Hastelloy or Tantalum?
    In high-temperature and highly corrosive environments, GR12 extends the equipment service life by 5 to 10 times compared to ordinary stainless steel, offering a highly economical solution compared to expensive Hastelloy and Tantalum.
