Vertical-Chamber Box-Type Tempering Furnace
Box-type tempering furnace is a batch-type electric furnace designed for high-performance tempering of alloy steel, carbon steel, and light alloys such as aluminum. With forced hot air circulation and precise temperature control, it ensures uniform heating and repeatable results, applications for aerospace, automotive, and general manufacturing.
| Process | Purpose |
| Tempering | Reduces hardness of quenched steel, improves toughness and plasticity, relieves internal stress |
| Solution & Aging | Increases strength of aluminum alloys and other light alloys |
| Annealing / Normalizing | Available on select models for versatile production needs |
Typical Applications
Materials processed: Alloy steel, carbon steel, stainless steel castings, ductile iron, aluminum die castings, and more.
Industries served:Automotive parts, aerospace components, machinery manufacturing, R&D labs, and pilot production.
Important Process Notes
Avoid 600–700°C for stainless steel: Prolonged holding in this range may cause embrittlement phases, reducing corrosion resistance and toughness. Adjust process parameters accordingly.
Plan for dimensional change: Stress relief during tempering can cause slight part movement. For precision components, allow machining stock or use fixturing.
