NACHI-FUJIKOSHI CORP.

1. Short processing time by high-temperature carburizing

2. Excellent feature of pulse vacuum carburizing (Pat. pending)

Comparison of carburized microstructures
(Carburizing depth: 0.7mm, Hardness: 550Hv)

3. Uniform carburizing depth

Example of uniform carburizing depth obtained in gear carburizing

Carburizing depth is uniform everywhere in effective zone

4. High-density Carburizing

High-density carburizing improve the fatigue strength and abrasion resistance
(Hardness of SCM515: 900Hv)
