Marvell Quench Oil – General Purpose Heat-Treatment Quenching Oil

Product Overview

Marvell Quench Oil is a high-quality, general-purpose quenching oil formulated for heat-treatment operations involving carbon steels, low-alloy steels, medium-alloy steels, and high-alloy tool and die steels. Designed to deliver consistent and reliable cooling characteristics, this oil ensures predictable hardening results while minimising distortion, cracking, or metallurgical defects.

Engineered for industrial heat-treatment furnaces, workshops, and steel fabrication facilities, Marvell Quench Oil provides an optimised balance between cooling rate, thermal stability, oxidative resistance, and uniform performance across repeated quenching cycles. It is suitable for a wide range of steels used in mechanical engineering, automotive components, toolmaking, heavy fabrication, forging, and precision machining applications.

Whether used for batch furnaces, open quench tanks, gas-fired furnaces, induction hardening stations, or conveyor heat-treatment systems, Marvell Quench Oil maintains its cooling profile and provides repeatable metallurgical outcomes. Its low-volatility base oils and enhanced anti-oxidation additives ensure long fluid life, reduced sludge formation, and cleaner system operation.

Key Features & Benefits

1. Consistent and Controlled Cooling Rate

Marvell Quench Oil is formulated to deliver balanced quenching action ensuring predictable hardness levels. It cools rapidly during the vapour and boiling phases, followed by uniform cooling during the convection phase. This consistency helps reduce metallurgical variability and delivers superior process control.

2. Suitable for a Wide Range of Steels

The formulation supports numerous steel types including:

• Low-carbon steels

• Medium-carbon and high-carbon steels

• Low alloy steels

• High alloy steels

• Tool steels

• Die steels

• Forged components
  Its broad compatibility makes it ideal for workshops handling mixed steel grades with varying hardening requirements.

3. Low Distortion & Reduced Cracking

Marvell Quench Oil’s refined cooling curve helps minimise internal stress buildup that causes warping or cracking. This makes it suitable for precision components that require tight dimensional tolerances, such as gears, shafts, dies, and cutting tools.

4. Superior Oxidation Resistance

The oil resists thermal degradation and oxidation even during prolonged high-temperature exposure. This reduces the formation of sludge, varnish, and acidic by-products, keeping the quench bath clean and extending oil life.

5. Extended Fluid Life

High-quality base oils and stabilisers extend the service life of the quench oil, reducing disposal frequency and lowering operational costs. Extended fluid life is especially valuable in facilities performing continuous or high-volume quenching.

6. Low Volatility

Low vapour loss ensures a safer working environment and maintains oil level stability in open quench tanks. It also reduces the frequency of top-ups and minimises exposure to fumes.

7. Excellent Thermal Stability

Marvell Quench Oil maintains its viscosity and cooling profile under repeated thermal cycling. This reliability ensures consistent metallurgical results across hundreds of quenching operations.

8. Clean and Uniform Surface Finish

The oil’s clean burn-off characteristics reduce soot and residue on freshly quenched parts, resulting in cleaner surfaces for later machining, grinding, coating, or polishing operations.

9. Reduced Sludge Formation

Formulated to resist sludge, lacquer and carbon deposits, which can affect bath performance and reduce heat exchange efficiency. Cleaner oil results in better quenching quality and lower maintenance costs.
