Product Description:
VQ vacuum quenching oil is uniquely formulated with highly refined mineral oil and various additives including coolant, brightener and antioxidant.
Features and Benefits:
1. Low saturated vapor pressure with no influence on vacuum effect.
2. Good thermal oxidation stability and long service life.
3. Stable cooling capacity in vacuum to ensure workpiece’s hardening quality.
4. No harmful substances to humans, healthy and environmentally friendly.
Applications:
1. Suitable for ball bearing steels, tool and mould steels in middle size with medium hardenability in a vacuum.
2. Optimum operating temperature range: 20-80℃.
