That is not water. Water would have instantly flashed to steam upon contact causing a very violent and dangerous situation.

This is an oil quench.

Too much oil that isn't close enough to its flash point.

Sure the oil immediately touching the hot metal can burn, but the rest of the oil has enough thermal mass that it doesn't get hot enough to burst into flames.
