Titanium Grade 7 Forging is an alloy that primarily contains 90-95% titanium and has 0.12-0.25% palladium for enhancement of corrosion properties, especially against acidic and chlorinated solutions. The chemical composition also comprises iron up to 0.3%, carbon up to 0.08%, nitrogen up to 0.03%, oxygen up to 0.25%, and hydrogen up to 0.015%, which will add to the strength and endurance of the overall material. Mechanically, Grade 7 titanium has 450-550 MPa in tensile strength, 275 MPa in yield strength, and an elongation around 20%. It is great for applications under heavy demand owing to its great strength-to-weight ratio and excellent resistance to corrosion.

Yes, Titanium Grade 7 (Ti-0.2Pd) is highly corrosion-resistant, especially in harsh environments like seawater and acidic conditions, due to the addition of palladium, enhancing its ability to resist corrosion.
Titanium Grade 7 forgings are commonly used in industries like aerospace, chemical processing, marine, medical, and power generation due to their exceptional corrosion resistance, strength, and biocompatibility in challenging environments.
Titanium Grade 7 forgings are available in various sizes and shapes, including bars, billets, rings, discs, and custom configurations, typically ranging from small to large diameters for different industrial applications.
Titanium Grade 7 Forging is characterized by excellent corrosion resistance. It is commonly applied in aerospace and chemical processing, as well as in the medical field. It is used for aircraft and engine components in aerospace for its strength-to-weight ratio. In the chemical industry, it is used for heat exchangers, reactors, and valves because it offers superior resistance to aggressive chemicals. Titanium Grade 7 is used in the production of certain medical implants, for example, joint replacements and dental devices where biocompatibility, resistance to corrosion, and durability are necessary for long-term performance within the human body.
