The advantage of quenching is that it allows for the rapid cooling of metal, resulting in a high level of hardness. This is particularly beneficial for achieving the desired mechanical properties in materials such as tool steel, die steel, high-speed steel, and ultra-high strength steel. Quenching in oil and vacuum environments can also result in a bright workpiece with good organizational properties and no oxidation or decarburization of the surface.
In vacuum oil quenching, the absence of oxygen during the process protects the parts and the oil from oxidation. It also reduces the combustion of the oil compared to conventional oil hardening methods. The oil's cooling efficiency and viscosity remain stable over time, improving reproducibility of results. The control of oil pressure and its cooling specifications allows for optimization of hardening conditions, finding the right compromise between speed and homogeneity, and therefore between hardness and deformation. Vacuum oil quenching is particularly advantageous for large-section parts or low-hardenability steel, as it offers a high cooling efficiency and a safety margin.
On the other hand, there are some disadvantages to quenching. Water quenching, while effective in achieving hardness, can lead to distortion and cracking of the metal. This can compromise the material and make it unusable. Additionally, gas quenching can result in a higher temperature gradient in the part, which may require adjustments to achieve the desired mechanical characteristics and reduce distortion. Gas quenching may not be efficient for low-alloy steel and massive parts as achieving core hardness can be difficult.
Overall, quenching offers the advantage of rapid cooling and increased hardness, but it also has some drawbacks such as distortion and cracking. The choice of quenching method, whether it is water, oil, or gas, should be made based on the specific material and desired outcomes.
