Frequently Asked Questions
What is GR12 titanium alloy?
GR12 titanium alloy (Ti-0.3Mo-0.8Ni) is a high-performance, corrosion-resistant material specifically designed for extreme corrosive environments, offering excellent resistance to reducing acids and stress corrosion cracking.
What are the mechanical properties of GR12 titanium alloy under ASTM B348?
According to ASTM B348, GR12 titanium alloy has a Tensile Strength of ≥485 MPa, a Yield Strength of ≥345 MPa, an Elongation of ≥18% in 50 mm, and a Reduction of Area of ≥25%.
How does GR12 compare to 316L stainless steel in acid environments?
GR12 offers superior corrosion resistance. For example, in boiled hydrochloric acid (20%), GR12's corrosion rate is <0.1 mm/y, whereas 316L stainless steel gets perforated. In wet hydrogen sulfide, GR12 has zero-stress corrosion cracking, while 316L cracks within 3 months.
What are the primary applications of GR12 titanium rods?
GR12 titanium rods are widely used in chemical acid pipelines, electrolysis tanks, petroleum refining desulphurisation equipment, electroplating heating pipes, and geothermal energy systems.
Is GR12 titanium alloy a cost-effective choice?
Yes. In high-temperature and highly corrosive media, GR12 lasts 5 to 10 times longer than ordinary stainless steel, making it a highly cost-effective alternative to expensive Hastelloy and Tantalum solutions.
