Product Overview

This series of vacuum tempering furnaces is engineered for aerospace, automotive, and tool steel industries. By using deep vacuum protection, it ensures the surface chemical composition of high-strength steel remains unchanged during tempering (up to 950°C), effectively preventing decarburization. Combined with segmented PID control, it enables precise microstructure management for consistent hardness distribution.

Key Advantages

• Anti-Decarburization: The vacuum environment prevents carbon loss, ensuring surface hardness and wear resistance are not compromised, reducing the need for post-process grinding.
• Mechanical Property Optimization: Superior thermal uniformity (±3°C) ensures accurate tempering cycles to achieve the ideal balance between strength and impact toughness.
• Minimal Deformation: Uniform heating and cooling rate control minimizes secondary distortion caused by thermal stress in complex components.
• Full Data Traceability: Automatically records temperature and vacuum parameters for every batch, meeting compliance requirements for high-end manufacturing.
