Product Overview
This series of bellows heat treatment furnaces utilizes advanced vacuum atmosphere protection technology. It is specifically designed for solution treatment and stress relief annealing of stainless steel (304/316L/321, etc.) and superalloy bellows. Equipped with a fully sealed stainless steel muffle tank, it ensures that bellows remain isolated from oxygen during heating (up to 950°C), resulting in a clean, mirror-bright surface without the need for pickling.
Key Application Values
- Performance Assurance: Effectively eliminates work hardening and residual welding stress, ensuring excellent flexibility and elastic modulus.
- Surface Integrity: High-vacuum or reducing atmosphere protection achieves mirror-bright annealing, preventing wall thinning or crack risks caused by oxidation.
- Fatigue Life: Uniform microstructure transformation significantly enhances the cyclic fatigue life of precision bellows under complex operating conditions.
- Wide Applications: Ideal for instrument bellows, vacuum bellows, automotive exhaust pipes, and heat exchanger tube bundles.
