Industrial Oil for Vacuum Heat Treatment
Vacuum Quenching Oil No. 1 and No. 2
Low-volatility quenching medium for vacuum heat treatment systems
No. 1 / No. 2
Vacuum Hardening
Low Volatility
Glossy surface
Vacuum quenching oils No. 1 and No. 2 are developed for industrial vacuum heat treatment systems. Their low volatility, low saturated vapor pressure, and thermal oxidation stability ensure reliable vacuum system operation, clean part surfaces, and consistent quenching quality. Bulk supply of large quantities, export shipments, and cooperation on OEM and private label are available.
Product Description
Vacuum quenching oils grades No. 1 and No. 2 are developed for metal heat treatment operations in vacuum furnaces. Their narrow distillation range and extremely low saturated vapor pressure help reduce evaporation and maintain efficient vacuum pumping during operation.
The products exhibit low volatility, good evaporation resistance, and thermal oxidative stability. These properties help maintain consistent quenching performance and provide longer service life under repeated vacuum heat treatment cycles.
After quenching, parts retain good surface brightness, with low oil carryover and easier cleaning. Typical applications include bearing steel, tool steel, die steel, medium-sized aerospace structural components, and other suitable steel workpieces.
