Vacuum Annealing Furnace for Titanium & Stainless steel

Equipment Overview

Engineered for the most demanding materials in modern manufacturing, our vacuum annealing furnace delivers controlled, contamination-free heat treatment for titanium alloys and stainless steel components. Whether you're producing aerospace-grade tubing, medical implants, or high-performance industrial parts — this furnace ensures every piece meets the highest standards of mechanical integrity and surface cleanliness.

Features

✦ True Vacuum Atmosphere — Zero Contamination

Titanium absorbs oxygen and nitrogen above 500°C, turning brittle and discolored. Our vacuum system maintains a working pressure as low as 10⁻³ Pa, ensuring a completely inert environment throughout the entire heating and cooling cycle. The result: bright metallic surfaces, preserved ductility, and zero hydrogen embrittlement.

✦ High-Temperature Capability Up to 1300°C

Designed specifically for the high annealing temperatures required by titanium alloys (typically 700–1000°C) and austenitic stainless steels (950–1150°C), with stable, uniform heating throughout the entire furnace chamber.

✦ ±1°C Temperature Control Accuracy

Precise PID control with K/S-type thermocouples and Siemens PLC automation ensures repeatable results across every batch — critical for aerospace, medical, and nuclear applications where tolerances are non-negotiable.

✦ Exceptional Temperature Uniformity — ±5°C

Multi-zone heating elements and optimized airflow design deliver consistent thermal distribution across the full chamber volume, eliminating hot spots and ensuring uniform microstructure transformation.

✦ Intelligent Automated Operation

A 10-inch color touchscreen with programmable process curves (up to 30 programs) allows your team to configure, monitor, and log every annealing cycle with ease. USB data export supports traceability and quality documentation requirements.

✦ Rapid & Controlled Cooling

Gas quenching with inert backfill (argon or nitrogen) enables precise cooling rate control, preventing sensitization in stainless steel and preserving the phase structure of titanium alloys. Cooling rates are fully programmable to match your metallurgical requirements.

✦ 72-Hour Unattended Operation

Triple safety interlocks — over-temperature shutdown, thermocouple failure alert, and vacuum leak detection — allow continuous production runs with complete confidence, day or night.
