Vacuum Annealing Furnace for Advanced Alloy Tubing

Advanced alloy tubing—typically utilized in cutting-edge sectors such as nuclear power, semiconductors, and petrochemicals—demands exceptionally high standards regarding surface quality, microstructural uniformity, and residual stress levels.

Vacuum annealing furnaces are essential for the heat treatment of these materials—including high-end titanium, zirconium, and nickel-based alloys—because they are highly reactive at elevated temperatures. Exposure to ordinary air leads to severe oxidation and carburization, or even catastrophic failure due to “hydrogen embrittlement” caused by the absorption of hydrogen and nitrogen. In contrast, an ultra-high vacuum environment not only completely excludes harmful gases and preserves a bright, oxide-free surface finish but also facilitates the volatilization and extraction of residual internal hydrogen and surface oil contaminants at high temperatures. This process achieves microstructural uniformity and significantly enhances the tubing’s toughness and corrosion resistance without compromising dimensional precision.

The RVA-557 vacuum annealing furnace is designed for the annealing, solution treatment, stress relief, and stabilizing treatment of various materials and components—including titanium alloys (such as medical-grade Grade 23 titanium), hydrogen storage alloys, and reactive or refractory metals. It is suitable for processing materials such as titanium alloys, electrical steel, electromagnetic alloys, stainless steel, heat-resistant alloys, copper and copper alloys, and other metals.

The specific technical specifications for the RVA-557 are as follows:
