Great quenching oil.
I've been using MR VOLCANO Parks 50 Quench Oil for Heat Treating Steel and Knife Steel for a few months now, and I'm very impressed with the results. I've been able to achieve much higher hardness in my steel than I ever could with water quenching, and the oil has also helped to prevent cracking and distortion. The oil is also very easy to use, and it doesn't require any special equipment. I would highly recommend MR VOLCANO Parks 50 Quench Oil to anyone who is looking for a high-quality quenching oil. Here are some of the pros of MR VOLCANO Parks 50 Quench Oil: Produces high hardness in steel Prevents cracking and distortion Easy to use Does not require any special equipment Made in the USA Here are some of the cons of MR VOLCANO Parks 50 Quench Oil: Can be a bit expensive May not be suitable for all types of steel Overall, I highly recommend MR VOLCANO Parks 50 Quench Oil to anyone who is looking for a high-quality quenching oil. It's easy to use, produces great results, and is made in the USA.

Great product, 3+liters, Not a Gallon, unsatisfactory delivery
The product is great and the result us amazing, however, Inacurare description, Not a Galon, watch the images, the nannies 3+ liter, max 3.5 quart of product, so where is the rest declared in the description? It is still 0.5 quart of expensive oil. Seal was broken. Unsatisfactory delivery. However happy, but cost me much extra time to wait.

“Good cooling oil, I recommend it.”
It’s an oil that meets the “three Bs” (Good, Nice, Almost Cheap). It cools high-carbon steel well. Since simple steels like 1084, 1095, 26C3, W1, W2, etc. (carbon steels) must be quenched in less than one second to fully transform into martensite, achieving 100% martensite ensures the steel reaches its full potential. The only difference between Park 50 and water or brine is that it doesn’t create as much internal stress in the steel, which helps prevent cracking and warping. It produces high hardness in the pieces. I used files to test HRC after quenching. I sanded the steel beforehand to remove decarburization and measured 62-64 HRC on the steels mentioned. Like any industrial oil, it is toxic, so avoid using it in enclosed spaces.
