  22. Heat Treating 4140 steel FAQ : anvilfire.com How-to.

    Don, Normally 4140 is an oil quench steel. In a section this large you cannot blow enough air to make difference. You might get away with a water mist spray. Carburizing also requires a quench to be hard and is VERY shallow, insufficient for an anvil. 4140 is pretty tough and those forks were already heat treated. I would use it as-is.
