Product Overview

This series of vacuum atmosphere pit furnaces is engineered for metal components requiring superior surface quality. The equipment features a fully sealed, high-temperature resistant stainless steel muffle tank. Combined with high-vacuum purging and reducing protective atmospheres (H₂/Ar/N₂), it ensures workpieces are completely isolated from oxygen during heating (up to 950°C) and cooling phases.

Key Application Values

• Stainless Steel (304/316L, etc.): Eliminates work hardening and internal stress while maintaining a mirror-bright surface, allowing direct transition to the next process.
• Copper Alloys: Resolves oxidation and discoloration issues in Beryllium and Oxygen-free copper, ensuring consistent conductivity.
• Precious Metals: Ensures extremely low oxidation loss, preserving the original luster of jewelry and luxury goods.
