Can you quench hunger?
The formal answer is that you satiate a hunger, and you quench a thirst – as @jwpat7.
Quench tends to mean pour water on, not necessarily to satisfy the need, as much as to cool it – of course, when it comes to thirst, the water or liquid will satisfy it too..
Should I quench after tempering?
Don’t quench after tempering. If you do, you just have quenched steel. Whenever you heat steel above the critical point “around a cherry red color” you are austinizing the steel, changing its form. This “resets” any heat treating completely.
What does quenching mean?
verb (used with object) to slake, satisfy, or allay (thirst, desires, passion, etc.). to put out or extinguish (fire, flames, etc.). to cool suddenly by plunging into a liquid, as in tempering steel by immersion in water. to subdue or destroy; overcome; quell: to quench an uprising.
Why tempering is done after quenching?
Tempering is usually performed after quenching, which is rapid cooling of the metal to put it in its hardest state. … Higher tempering temperatures tend to produce a greater reduction in the hardness, sacrificing some yield strength and tensile strength for an increase in elasticity and plasticity.
Can you use vegetable oil for quenching?
Vegetable oils used for cooking are relatively inexpensive, completely biodegradable and non-toxic. … Depending on the quenching temperature, different vegetable oils may be selected which perform best at yielding the required mechanical characteristics at a given temperature.
How long does quench oil last?
10 yearsQuenching and martempering oils deteriorate during use, although most premium quenching oils can last more than 10 years when given reasonable use and care.
What happens during quenching?
Quenching involves the rapid cooling of a metal to adjust the mechanical properties of its original state. To perform the quenching process, a metal is heated to a temperature greater than that of normal conditions, typically somewhere above its recrystallization temperature but below its melting temperature.
What is quenching oil used for?
Quench oil serves two primary functions. It facilitates hardening of steel by controlling heat transfer during quenching, and it enhances wetting of steel during quenching to minimize the formation of undesirable thermal and transformational gradients which may lead to increased distortion and cracking.
Which quenching medium produces the slowest quench?
Liquid cooling starts when the surface temperature of the metal reaches the boiling point of the liquid so that vapor is no longer formed. This is the slowest stage of cooling.
What is the difference between quenching and hardening?
Quenching is a very rapid cooling whilst hardening might include one or several processes that are increasing the strength of the material. … Hardening is a complete process of heating, soaking and rapid cooling. Quenching or rapid cooling is just one stage of Hardening.
Why is quenching important?
In materials science, quenching is the rapid cooling of a workpiece in water, oil or air to obtain certain material properties. A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring.
What is the difference between tempering and quenching?
The process of quenching or quench hardening involves heating the material and then rapidly cooling it to set the components into place as quickly as possible. … Tempering is achieved by heating the quenched material to below the critical point for a set period of time, then allowing it to cool in still air.
Why do blacksmiths put metal in water?
Blacksmiths put metal in water because water submersion will allow the forger to control the brittleness and overall strength of the metal. This is referred to as “quenching,” and is used by many blacksmiths to decrease the risk of breakage when crafting new pieces.
Why is quenching in oil better than water?
Water quenching is a rapid cooling, where water as a qenching medium extracts heat much faster. While oil as a medium will extract heat much slower, hence rate of cooling will be slower than water. … Oil cooling will generate lesser stress and moderate hardness.
What oil is used for quenching?
The two most common food grade oils used in this process are peanut and canola oil. Both of these oils have high flash points which is good for the quenching process. You will need to preheat these oils to slightly higher temperatures when compared to commercial quenching oils (120 – 130 degrees Fahrenheit).
