Quench size

[Sharpe5097]

If I am quenching 1095 steel, how much fluid should I be quenching it in. I am currently using Kubota super udt hyrdolic fluid in a one gallon paint can.

1095 is a water quench steel. That being said, in thin sections (i.e. a blade thickness) a fast oil will harden most water quench steels.
Not being familiar with your oil, I suggest you take a scrap of 1095, heat it to austinizing temp and quench it in the hydraulic oil. Heat the oil to 130 to 140°f prior to quench. Go from heat to quench in less than a second. Then test it.

PS
a gallon should sufficient, as long as the quench tank is deep enough to allow complete emersion of the knife blade.

Ideally, as much oil as possible.

The larger the volume of oil, the more knives you can quench without it overheating.

I think my ammo can holds 4 gallons, and it seems to work well.

Okay. Thank you

You're using hydraulic fluid of unknown quench properties that's actually more expensive than parks 50.

Other than using what you've got I just don't get it.

I think you're better off with 120 degree canola. Cheaper, less dangerous fumes, known to harden 1095. A gallon being the minimum.
