Vacuum Carburizing

Controlled and Reproducible

Vacuum carburizing provides customers with complete uniformity by allowing us specify details for case depth, surface and core hardness, carbon profiles, and core microstructure. Parts emerge from this process essentially free of intergranular attack or other surface reactions, and consequently do not post heat treat grinding operations. Our Portland location is home to one of the world’s largest vacuum carburizing furnaces, with a working zone of 70” x 70” x 84” and with a load capacity up to 10,000 lbs.

Benefits of Vacuum Carburizing

Eliminates surface intergranular oxidation
Excellent case uniformity for complex geometries
Precise, alloy-specific process controls
Highly repeatable case depth control
