Zirconium 702 Pipes

ZR 702’s Properties and Performance in Demanding Environments

Hello. This is Dong-A Special Metals Co. Today we present an in-depth look at Zirconium 702 (ZR 702)—the most widely used commercially pure zirconium alloy known for its superior corrosion resistance and mechanical strength.

ZR 702 is composed of over 99.2% high-purity zirconium, with very low levels of iron, chromium, nickel, and hafnium. These controlled impurities enhance the metal’s chemical stability and corrosion resistance. With a density of 6.51 g/cm³ and a melting point of 1852°C, ZR 702 is lightweight yet highly heat-resistant.

It exhibits outstanding ductility and machinability, with more than 20% elongation. The alloy features a tensile strength of approximately 379 MPa and a yield strength near 207 MPa.


Industrial Applications and Strategic Importance of ZR 702

ZR 702’s most notable property is its exceptional corrosion resistance. It performs reliably in strong acids like sulfuric, hydrochloric, and phosphoric acid, as well as in organic acids and seawater. Even under wet base conditions and high-temperature steam, its oxide film remains stable, making ZR 702 a key material in harsh chemical and marine environments.

ZR 702 is widely used in:

- Chemical process equipment

- Heat exchangers, reactors, and piping systems

- Valves, pump linings, and cladding materials

- Nuclear power components, such as fuel rod cladding and heat transfer systems

In nuclear applications, ZR 702 provides high radiation resistance and long-term durability. Its performance in oxidizing environments makes it a preferred choice for pressure vessels and advanced reactor designs.


Recycling Value and Supply Chain Impact

Zirconium is classified as a rare metal. Its mining and refining involve high costs and environmental impacts. That’s why ZR 702 scrap recycling is gaining strategic importance for resource circulation and carbon reduction.

At Dong-A Special Metals, we are advancing technologies for zirconium scrap recovery and remelting, especially in semiconductor and nuclear sectors. ZR 702, along with Zircaloy-4 and ZR 705, offers high recycling value due to their cost and functional performance. These alloys contribute to a sustainable metal circulation system while lowering environmental burdens.

ZR 702 is the most versatile zirconium alloy available. Its performance across multiple sectors, including chemical, marine, nuclear, and semiconductor industries, makes it a strategic material for Korea. Demand for this alloy is expected to grow as industries seek corrosion-resistant and stable metals.

We believe that expanding zirconium recycling will help stabilize Korea’s supply chain and reduce reliance on imported materials. Dong-A Special Metals is proud to lead this transformation by improving material processing and recycling efficiency.
