Oil blacking is reasonably stable and doesn't require any additional sealing, although a layer of hard wax, reapplied every so often will make it a bit more durable. Keep water out of your oil quench. Quenching describes the sudden immersion of a heated metal into cold water or oil. In case you’re unsure about what kind of oil you should be using to quench, as a general rule, here’s the recommendations for types of oil to use when quenching different materials: Fast quench oils (6-9 seconds): W1, W2, 1095, 1084, 1080, 1075, 15n20 Beware of flare up when quenching hot steel---get in under the surface fast! Please keep a lid on the oil quenching container to keep out all kinds of floating crud and also animals that could drown in the oil (& make a really smelly mess).Light also speeds up some oxidation reactions, so keep a lid on the container when not in use. Mineral oil, canola oil, peanut oil, actual quenching oils, but never motor oil, especially used motor oil. On the other hand, fast quenching oils are great for steels with high critical rates. Prunus amygdalus Batsch., Amygdalus communis L., Amygdalus dulcis Mill. Water quenches especially accumulate crud in the bottom that change the content of the water. In the early day of the industrial revolution, whale oil was used, not a good idea these days. When using hot quenching oils, it is necessary to make an allowance for thermal expansion of the oil, either by making provision for an overflow system, or by manual adjustment of the fluid level. As a novice blade smith, I REALLY value the education. A locking device will keep the raccoons away, hopefully. As the oil oxidizes it will begin to increase in viscosity until it reaches the point of forming an insoluble sludge. Water is an effective medium when the goal is to make the steel strong. An oven heats metal components to extreme temperatures and then submerged in a liquid bath for rapid cooling. The SCM435 steels were annealed at 880 °C for 60 min with quenching into oil and then tempered at 520 °C for 60 min to make the tempered martensitic steels. $50 Knife Shop suggests the oil should be 90 – 140F , but I just used my finger to judge when the oil became bath-water warm. Part of the reason for oil quenching is rust prevention, and there is no need to do this with a stainless steel metal. Thanks, I certainly will get a quenching oil. To all who replied to my posting on quenching oil, my many, many thanks. Salt poses greater quenching benefits than oil. I have used 52100 a bit and I've had good hardness quenching in peanut oil. If you have ever been to a real blacksmith’s forge or watched one of the popular metal-working reality TV shows, you likely have seen the professionals using quenching heat treatments such as oil quenching.It differs from other common steel heat treatment processes such as case hardening, … 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. EASTTO QUENCH HS 70 is high speed quenching oil blended from highly refined paraffinic base oils and special additives to optimize heat resistance to the oxidation and to adhere to the surface of the working piece by providing bright finish due to reduced sludge forming tendencies with … Oil gas mineral rights lease questions. It has stuff added that can ruin a quench, especially used motor oil which almost always has water in it. A Note About the Oil: We don't want to put the hot sword directly into cold oil. I did suspect that the used-motor-oil was a myth of sorts. This is a process that strengthens and hardens iron-based alloys by heating, rapidly cooling, and reheating. Along with the wetting agents, a complex antioxidant package is added to maintain the oil's quenching speed, and viscosity, for long periods of continued use. Heat your oil to around 130 degrees F, just hot enough you don't want to leave your finger in it more than a second or so. Quenching is the rapid cooling of a heated metal in a quenching medium such as water, oil or air in order to obtain desirable material properties. Oil quenching works best for knives, blades, and some hand tools because these types of steel are generally rated for oil quenching. A few pounds of water at the bottom of an I quench trank can cause a major fire. Oil Quenching. For the quenching fluid you can have used motor oil, used transmission fluid or vegetable oil. I asked this question several months ago (torch/forge heating, with oil quench, heat treat of 440C), and was fortunate to get an Ed Fowler answer. I've also marquenched it but, according to Kevin, there might be a problem with the rate of heat transfer with the oil that hot. Absolutely you can oil quench 440C. Oil and Water Don’t Mix. A high- quality quenching oil is formulated from refined base stock with a high paraffinic content. I did discover that canola oil beats olive oil because canola has a higher flash point thus making it conduct heat more evenly before catching fire. When is quenching used? Almost any oil will do the job. Steel is strong to begin with, but sometimes it’s necessary to make it even stronger. Oil quenching. The almond (Prunus dulcis, syn. Things You Should Know: Quenching Metal – Explained January 15th, 2018. In metallurgy, quenching is one of the critical steps in the heat treatment of a metal and is typically used to harden the final steel product. However, the quenching process can be incredibly delicate so choosing the ideal oil can be the difference between your creation breaking right away or lasting a lifetime. Quenching salts can come in a mixture of elements. 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. I use atf fluid. However, the use of water can cause metal to crack or deform. A quenching oil for blacksmithing could be many things, including dedicated quenching oils or miscellaneous oils you may use for your car or cooking. I don't know about soaking the steel at 1650° for normalization. Selected wetting agents are added to the base stock to ensure proper quenching rate. As an oil is subjected to the high temperatures of a quenching operation, oxidation is a natural occurrence in the oil. Temperatures, water content, and agitation are easier to control. Quenching oil serves two primary functions. Interesting to see that one can actually get carbon back into steel (but obviously over extended periods under heat). I have found some coil springs, which should be 1095 of the likes, and with some luck I will have a lot of leaf springs too in a week or so. Quenching oil for blacksmithing comes in many forms also. Vegetable oil is good,but NOT USED vegetable oil. Quenching is usually used with metals that are alloyed with small amounts of other metals. Oil, next only to water, is the most widely used quenchant because of its versatile quenching performance. The conventional quenching oil type is good for those steel types that have low critical cooling rates. used fry oil is generally ok; you will want to use it warmed to about 140 degF Should be OK for 5160---what size item? You will need a LOT of it for large items. Salt can sometime be recovered and reused, whereas oil, is harder to reuse. Back to Blog. One of the common treatments to achieve this is quenching and tempering. Quench oil serves two primary functions. It will have salt and other stuff in it that can hurt your project. Quenching is the process of rapidly cooling a material (usually a metal) in order to obtain desirable mechanical properties like increased strength and hardness. Submitted by Combustion Innovations.
