Heat treatment oil

‌Heat treatment oil is a specialized quenching medium used in metalworking processes to control the cooling rate of heated metals, ensuring optimal hardness, strength, and durability. It plays a crucial role in heat treatment operations such as hardening, tempering, annealing, and normalizing.

‌Key Features of Heat Treatment Oil:‌

‌Controlled Cooling Rate‌ – Different metals require specific cooling speeds to achieve desired mechanical properties. Heat treatment oils are formulated to provide precise cooling rates.
‌Thermal Stability‌ – High-quality oils resist oxidation and thermal degradation, even at extreme temperatures, ensuring consistent performance.
‌Minimized Distortion & Cracking‌ – Proper quenching reduces internal stresses, preventing warping or cracking in treated parts.
‌Long Service Life‌ – Premium-grade oils have additives that extend usability, reducing maintenance costs.

Ordinary quenching oil

It has good thermal oxidation stability and a long service life of the oil. It has good rust resistance.
Longer cooling characteristics retention, the performance of Maxtop ordinary quenching oil is significantly better than the comprehensive performance of other similar products on the market. Super long service life.
Long-term use will not produce sediment and sludge. Long-term use will keep the viscosity stable and will not thicken.

Applications

It is suitable as a cooling medium for quenching processes such as steel (especially alloy steel) and other alloy materials. Ordinary quenching oil is used for quenching materials of small size and good hardenability.

Rapid quenching oil

The steam film stage is short, the high temperature cooling capacity is large, and it has strong hardening and hardening capabilities. The oil is less consumed, easy to clean, and the cost of use is low.
Good thermal oxidation stability, stable oil performance and long service life. No sediment and sludge will be generated after long-term use.
The viscosity remains stable and will not thicken after long-term use. With ultra-long cooling characteristic retention, the performance of Maxtop rapid quenching oil is significantly better than the comprehensive performance of other similar products on the market. Ultra-long service life.
The oil film is evenly distributed, the internal stress of the workpiece is reduced, and the deformation rate is reduced by 60%. Complex parts processing: mold, crankshaft, camshaft, etc.

Applications

Rapid quenching oil is suitable for quenching parts such as tempering and carburizing that require high cooling speed, large forgings, large gears and quenching presses in salt bath furnaces, box furnaces, medium furnaces and continuous quenching furnaces.

Ultra-fast quenching oil

The maximum cooling rate is high, which can make the workpiece obtain sufficient hardness and hardened layer depth after quenching.
The cooling rate at 300℃ is significantly improved, and can be controlled at 15~30℃/S according to customer requirements.
Good thermal oxidation stability, can maintain long-term stable cooling performance and long service life.
Super-speed quenching reduces oil consumption, makes it easy to clean parts, and can greatly improve the working environment.
Long-term use will not produce sediment and sludge. Long-term use will keep the viscosity stable and will not thicken.
Avoid contact with water, otherwise it will cause emulsification and deterioration.

Applications

It is mainly used for heating quenching, carburizing or carbonitriding quenching of large parts in automobile, bearing, mining machinery, metallurgical machinery and tooling industries. It is also suitable for quenching medium carbon steel and other alloy steels.

Water-based quenching liquid

When the concentration used exceeds 5%, the workpiece has a good anti-rust effect after quenching.
It is safe to use, non-toxic, harmless, clean and environmentally friendly, not easy to age or deteriorate, and has a long service life.
It is miscible with water in any proportion, and the cooling speed can be adjusted arbitrarily to meet different cooling performance requirements.
The quenching hardness is high and the quenching layer is uniform, which greatly reduces the quenching deformation of the workpiece and avoids the risk of quenching cracks and soft spots.

Applications

Suitable for overall quenching of carbon steel, alloy steel, cast iron, high chromium cast iron, heat treatment of forgings, etc. Solid solution treatment of aluminum alloys.

Isothermal graded quenching oil

High flash point and high ignition point can realize isothermal graded quenching of martensite, which can effectively reduce the quenching deformation of parts and thus improve product precision.
Excellent thermal oxidation stability, can maintain long-term stable cooling characteristics, and has a long service life under high temperature conditions.
It has strong cooling capacity, moderate high-temperature cooling rate, and slow low-temperature cooling rate. It is especially used in the quenching process of controlled atmosphere furnace, which has a more obvious brightening effect on the workpiece surface.
The hardness of the workpiece is uniform after quenching, which can obtain both high and uniform surface hardness and sufficient hardened layer depth.

Applications

It is suitable for quenching materials such as alloy steel, carburizing steel, as well as bearing inner and outer rings made of bearing steel and carburizing steel, precision parts, automobile gears, half shafts and other workpieces as well as easily deformed parts.

Tempering oil

It has good thermal stability and is not easy to coke. The appropriate cooling rate can effectively eliminate the internal stress of the workpiece.
It has the characteristics of high flash point and low volatility, and is not easy to evaporate and form smoke, creating a good use environment.
After tempering, the workpiece has uniform hardness and bright surface.
It has good thermal oxidation stability, is not easy to form sludge and oil residue, and has a long service life.
After tempering, the surface is bright without rust spots, and the hardness uniformity is increased by 20%.
The low volatile formula reduces oil mist diffusion and keeps the workshop air clean.

Applications

Tempering oil is suitable for tempering parts after quenching in closed tempering furnaces. It is widely used in the tempering process of bearings, watches, chains and other industries.
