What quench oil is used on forged in fire?

If you want to use vegetable oil for quenching, coconut oil is a great option. Not only is it an effective quenching oil, but it will also leave your forge smelling great. Generally, vegetable oils are a good option for at-home blacksmiths, as they are widely accessible and easy to use.

What kind of oil do they quench with on forged in fire?

1) Motor Oils

Motor oils are a common type of quenching oil used in both blacksmithing and bladesmithing applications. New and used motor oils can be used for quenching and are both widely available.

What kind of oil do you quench hot steel in?

Mineral and transmission oils

Mineral oil quenchants are excellent for oil-hardened steels and steels that require a fast quench rate. They tend to be on the expensive side, but they're highly efficient and have greater cooling capacities for steel alloys.

What motor oil is best for quenching?

Canola, Motor Oil, and the Inconel Probe Test

I found a study on 1045 steel where they found canola to quench more rapidly than motor oil so I am going to stick with canola as my “cheap” quenching option to test.

What do blacksmiths use to quench?

Blacksmiths generally use water, oil, or compressed air to quench. These substances vary in environmental impact, cost, and effects on the metal, but the best quenching medium is usually water or quenching oil.

How hot does oil have to be to quench?

Quenching into oil above 212°F (100°C) has traditionally been referred to as "hot oil" quenching. Oil temperatures in the 195°F - 450°F (90°C - 230°C) range have been used with both ends of the spectrum normally reserved for special applications.

Can you quench 80CrV2 in canola oil?

Heat treating 80CrV2: heat to 830 C (1525 F) hold for 10 mins for "knife blade thickness" Quench in a fast quench oil (not Canola)

Why do you preheat quench oil?

I figure preheating the oil does one of two things. It either lowers the shock for the quench, making fractures and bends less likely (hope it's this one, because it didn't happen) or it hardens better because it makes the oil less viscous, meaning it can transfer heat away from the blade better.

What does putting red hot steel in oil do?

Parts made of low-carbon steel and low-hardenability alloys quench better in fast oils. Hot oils are kept at much higher temperatures and are used to ensure that a part's core temperature and surface temperature do not vary too greatly during a quench. This controls distortion and reduces the risk of cracking.

Why are blades quenched in oil not water?

Oil has a slower rate of cooling compared to either water or brine, but faster than air, making it an intermediate quench.

Do they get to temper the blades on forged in fire?

Contestants are given 3 hours to forge a bar into a blade profile, which then is supposed to be 'tempered' (as I will elaborate on, this is in fact quench hardening only). Sometimes they start with a fixed material not shown until they start, sometimes they can select from several types.

What is the difference between oil quenching and water quenching?

Water-quenched steels will generally be harder than oil-quenched steels. This is mainly because the thermal conductivity of water is higher than the thermal conductivity of most oils (that I know); consequently, the rates of cooling will be less rapid (or lower) in oils compared with water.

How long does quench oil last?

Oil Recovery

Quenching and martempering oils deteriorate during use, although most premium quenching oils can last more than 10 years when given reasonable use and care.

How do you harden steel oil?

One way to do this is to make the steel red-hot, then plunge it into motor oil. The carbon in the motor oil bonds with the top layer of red-hot steel molecules and forms a tough outer covering on the steel. One last step is necessary, however, before your hardened steel is ready to work with.

Is Parks 50 a fast quench oil?

Parks 50 is considered a fast oil. Many times a quench oil is described in seconds quenching using a Nickel Ball test. The Nickel Ball quench time is 7-9 seconds.

What temperature do you quench steel?

The steel is tempered to reduce some of the hardness and increase ductility. It's heated for a set period of time at a temperature that falls between 400° F and 1,105° F. Sometimes, if further ductility is needed, a higher temperature is used- around 1,300° F.

Does quenching make metal brittle?

Quenching results in a metal that is very hard but also brittle. Gently heating a hardened metal and allowing it to cool slowly will produce a metal that is still hard but also less brittle.

What is 80CrV2?

80CrV2 steel is a traditionally cast, high-carbon tool steel that contains chromium as well as vanadium in quantities high enough to affect the strength and hardness of the crystalline matrix of the steel. Vanadium is an element that is added to steel alloys that are typically used to produce excellent edge retention.

Is 80CrV2 hard to heat treat?

80CrV2 is some of the finest grained and toughest steels I've ever used. It is unusually difficult to break 'as quenched' coupons with no tempering to look at the grain. I've tried tempering down to 300 F. but ended up walking back up to about 350F. or so.

Can you quench 1095 in canola oil?

IF one were to quench 1095 in vegetable oil. make sure that it is canola, and that its at least 120F (140F is better) hot before you quench into it. also make sure to grind the steel thin before heat treating.

What liquid is used for quenching?

Water is one of the most efficient quenching media where maximum hardness is desired, but there is a small chance that it may cause distortion and tiny cracking. When hardness can be sacrificed, mineral oils are often used.

How do you choose quenching oil?

The selection of quench oil can be accomplished by one or more methods: Comparative Cooling Curves; Hardening Power, or by the Grossman H-Value of the quenchant. In each case, not only must the quenching characteristics be considered, but the thermal stability of the oil should be considered.

How do you harden steel at home?

Set your steel directly on the oven rack or on a baking sheet. Let your oven heat the piece of steel. During the tempering process, the steel heats up enough to soften the alloys inside to make it less brittle. If you need to use a blow torch, focus the flame tip on the area you want hardened.

Which quenching medium is commonly used?

Oil is the most popular quenchant because it is relatively severe but with a diminished risk of cracking and warping. In addition, a wide range of parts quenches well in oils because the chemical makeup and temperature of a quenching oil can be adjusted to suit desired end results.
