Titanium Grade 7 Sheets – Composition & Material Specification
What is Titanium Grade 7 Sheet?
Titanium Grade 7 sheet is a high-quality titanium alloy that is known for being very strong, resistant to corrosion, and durability. It is an alloy of titanium and palladium, and adding a small amount of palladium makes it much more resistant to reducing acids and harsh chemical environments. Due to this, Titanium Grade 7 is often chosen for uses where regular titanium grades might not work as well.
Titanium Grade 7 is made up of 0.08% carbon, 0.30% iron, 0.03% nitrogen, 0.015% hydrogen, 0.25% oxygen, and up to 0.20% palladium. The rest is titanium. These controlled limits ensure that performance stays stable and quality stays consistent across all applications. The alloy has a density of 0.163 lb/in³ and a melting point of about 1668 °C. It has a tensile strength of about 39,900 psi (275 MPa), a yield strength of 59,500 psi (410 MPa), and an elongation of about 20%, which means it is both strong and flexible.

Application Industries of Titanium Grade 7 Sheet
As they are very resistant to both oxidizing and reducing environments Titanium Grade 7 sheets are commonly used in chemical processing equipment, marine systems, and heat exchangers. The alloy works very well in places where there is high amounts of chloride. This means that it can be used in tough marine and offshore situations. As it is very durable and resistant to localized corrosion it lasts longer and costs less to maintain.
Industries such as oil and gas, power generation, desalination, and aerospace frequently rely on UNS R52400 Titanium Sheets for critical components where purity, corrosion resistance, and minimal contamination are essential. Additionally Ti Alloy GR.7 Hot Rolled Sheet is known for its good fabricability and weldability. This allows designers and engineers greater flexibility during manufacturing and installation.
