Gr.7 Titanium Alloy Rod For Strong Acid Environments Piping For Nuclear Industry

Gr.7 Titanium Alloy Rods - Reactors for Strong Acid Environments, Piping for Nuclear Industry

Product Overview

Titanium Alloy Grade 7 rods, designated as UNS R52400, are renowned for their exceptional corrosion resistance, particularly in reducing and oxidizing environments. This superior performance is primarily due to the addition of palladium (0.12–0.25%) to commercially pure titanium, enhancing its resistance to aggressive media such as hydrochloric and sulfuric acids. Maintaining the mechanical properties of Grade 2 titanium, Grade 7 offers improved durability in challenging conditions.

These rods are extensively utilized in industries where corrosion resistance is paramount, including chemical processing, marine engineering, and medical applications. Their ability to withstand harsh environments makes them ideal for components like heat exchangers, reactor vessels, and piping systems. Additionally, the biocompatibility of titanium ensures suitability for medical implants and devices.

Conforming to ASTM B348 standards, Titanium Grade 7 rods are available in various sizes and finishes, catering to diverse application requirements. Their combination of strength, corrosion resistance, and formability positions them as a reliable choice for critical applications across multiple sectors.
