ZYTC Alloy, a professional and reliable Chinese nickel-based superalloy manufacturer and supplier, provides high-quality Rene 62 wrought precipitation-hardening nickel-based superalloy in diversified forms including bar, plate and forging.

Produced via strict vacuum smelting processes, Rene 62 features excellent high-temperature oxidation resistance, outstanding weldability and superior high-temperature plasticity. Characterized by a slow age-hardening reaction, this alloy avoids excessive hardening brittleness during service and exhibits extremely stable comprehensive performance.

Rene 62 is widely recognized as an ideal material for high-stress welded structural parts, high-temperature thermal forming dies and a variety of aero-engine high-temperature components.

Superior Temperature Resistance & Mechanical Performance Advantages

Rene 62 boasts an extreme maximum service temperature of up to 813°C. When operated continuously at temperatures below 730°C, its tensile strength and yield strength are significantly superior to mainstream superalloys such as Inconel 718 and Rene 41, delivering more reliable load-bearing performance and longer service life under long-term high-temperature and high-load working conditions. Featuring a slow age-hardening reaction and excellent high-temperature plasticity, the alloy effectively avoids brittleness issues and performs exceptionally well in high-stress welded structures and hot forming applications.

The alloy maintains balanced strength and ductility at both room temperature and elevated temperatures, with stable and standardized mechanical parameters as shown below:
