Deformation Control
General-purpose industrial quenching oil designed for stable cooling, uniform hardening, and consistent surface quality of parts. Ningbo MOS Chemical Co., Ltd. supplies it to heat treatment shops, distributors, importers, and industrial buyers through B2B wholesale, bulk procurement, and OEM or private label cooperation.
Manufacturer and Supplier of Universal Quenching Oil
General-purpose quenching oil is designed as an industrial cooling medium for heat treatment, intended for applications requiring stable cooling, uniform surface hardness, and controlled workpiece distortion. It can be used for various small and medium-sized alloy steel, carburized, and nitrocarburized workpieces.
Compared to using conventional mechanical oil as a quenching medium, this specially formulated product provides more stable cooling characteristics and improved oxidation stability. It supports quench hardness and case depth while helping to maintain surface cleanliness for subsequent processing such as galvanizing.
The specified operating temperature range is 20–100°C. The actual product selection and bath operating mode must be determined based on workpiece material, dimensions, required hardness, permissible distortion, agitation conditions, and heat treatment process.
MOSINTER GROUP is an industrial investment group that invests in production facilities and supply chains. Ningbo MOS Chemical Co., Ltd. manages international B2B supply, wholesale procurement, distributor cooperation, and negotiations on OEM and private label projects for buyers of industrial oils and heat treatment fluids.
- Stable Cooling for General Heat Treatment Processes
- Good oxidation resistance helps extend service life
- Ensures uniform hardness and depth of hardening
- Clean workpiece surfaces facilitate subsequent processing
