Introduction

Vacuum annealing furnace is a specialized heat treatment system designed to perform annealing processes in a high-vacuum environment. It is ideal for relieving internal stresses in metal materials, improving ductility, and refining microstructures. The equipment enables bright annealing without surface oxidation or decarburization, making it widely used in industries such as aerospace, precision manufacturing, electronics, and medical devices.

Applications

  • Vacuum annealing of stainless steel, alloy steel, titanium alloy, and other metals
  • Stress relief heat treatment after welding or cold working
  • Bright annealing of precision components (e.g., electronic packaging parts, medical components)
  • Post-processing of 3D printed metal parts and high-temperature alloys
