Quench oil serves two primary functions. When selecting the oils, one must look into the list of properties, features, and chemistry of the fluid. Vac Aero International Inc. - Oil Quenching Technology, Machinery Lubrication - Quenchant Fundamentals: Condition Monitoring of Quench Oils. AAA Quench Oil is suitable for integral quenching and ideal for carbon, low and medium alloy steels. This property does not give any information about the cooling pathway, however (as demonstrated in figure 3); it merely gives the time required to cool to a certain temperature. Heat transfer is fastest during this stage, with heat transfer coefficients sometimes over two orders of magnitude higher than during film boiling, largely due to the heat of vaporization. Let’s take a brief glance at the history behind quenching. Reduction in consumption by drag out. Image Credit: Machinery Lubrication. The points at which this transition occurs and the rate of heat transfer in this region depend on the oil's overall molecular composition. Pail. Quenching Oil Hs 70 is recommended when deeper and more uniform hardening is required in steel, particularly lean in alloy content. UNLIMITED

Additive type Quenching oil Quenching can be done in water, oil, or in a martempering bath, depending on the type of steel used. A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring. The company also produced oil for industries, metal fluids, quenching and heat transfer. The stability of the vapor layer, and thus the ability of the oil to harden steel, is dependent on the metal's surface irregularities, oxides present, surface-wetting additives (which accelerate wetting and destabilize the layer), and the quench oil's molecular composition (including the presence of more volatile oil degradation by-products). Cooling rate during this stage is slow, and is exponentially dependent on the oil's viscosity, which varies with the degree of oil decomposition. Quenching oil serves two primary functions. Heat-transfer rates increase with lower viscosities and decrease with increasing viscosity. In flush quenching, the whole surface including all irregularities (cavities or recesses) is sprayed using quenching liquid, at different rates to ensure a uniform rate of cooling over the whole object. When heat treatment fluids are used to quench metals, cooling occurs in three distinct stages: film boiling, nucleate boiling and convective heat transfer. Quenching speed adapted to your heat treatment cycles | Design by Sahavas, Excellent Resistance to oxidation and enhanced oil life, Reduced consumption due to lower volatility characteristics and minimum drag out, Reduced fire hazard due to excellent high temperature characteristics, Provides uniform hardness without distortion.

Increasing Nb concentration in Ti 3 Al upon oil quenching allows retaining high-temperature B2 phase up to room temperature. Caustics are the most severe quenchants, followed by oils, then salts and, finally, gases. The company also has a tie up with several other companies for genuine oils. Generally, low-hardenability parts made from carbon steel and low-alloy steel require more severe … GlobalSpec collects only the personal information you have entered above, your device information, and location data. When the part has cooled below the boiling point of the quenchant, slow cooling occurs by convection and conduction (also called the "liquid" stage). Properties for describing heat treating fluids can be classified as either primary or secondary. With wrought, case and forged aluminum alloys Ltd. © Copyright 2021 GlobalSpec - All rights reserved. As the part cools, the vapor blanket collapses at points and nucleate boiling (violent boiling of the quenchant) results. 4) or, if using a polymer quenchant, by reducing the concentration of the solution. PDS No. Their low volatility characteristic reduces oil loss from the vaporisation and the uniform heat dissipation property minimises stress and metal distortion ensuring uniform hardness. The high initial cooling rates allow for the development of full hardness by quenching faster than the so-called critical transformation rate and then cooling at a slower rate as the metal continues to cool. Marquench Oil are suitable for usage at bath temperatures of 150°C to 220°C and are recommended for all marquenching operations which require high quenching speed e.g., mass production of high precision products such as automotive gears, bearings, tools, dies etc. with low distortion due to quenching. Image credit: Vac Aero International Inc. PDS No. If extreme hardness isn't necessary, mineral oil, whale oil, or cottonseed oil may be used in the quenching process instead. This causes the slower convective cooling stage to start sooner, enabling the release of transformation stresses which is the major problem with rapid water cooling. Stability in service. But in today's quality and environment-conscious quenching oil. These quenching oils and polymers have been developed to ensure better control of cooling cycles:. These include cooling rate, thermal conductivity, viscosity, water content, and sludge formation. 2. Primary properties are those which describe the performance of the fluid. The boiling point of the quenchant determines the conclusion of this stage. Different types of oil are often used depending on the application because of their varying cooling rates and flash points.
