Shouldn't be any serious decarb then if you only hit a guessed at 1600 degrees and a simple air cool is what is called for. Try this Rasmus, grind off about 0.1 mm and see how much a file digs in then. If there was some decarb it probably wouldn't be deeper than 0.1 mm or .004" deep. The blade might be hardened under a layer of decarb. It's worth a try.

By the way as to guessing forge temps you can take a lot of the guesswork out by using Tempil Markers, they're not listed on their website, but they have markers that go up to 1800 in jumps of 50 degrees. My brother bought 1450, 1500, 1550 and 1600. If the temp is below 1450 the stick tip doesn't melt. So you can figure out your temperatures pretty closely. Also since they are the size of a marking pen shipping from the USA shouldn't be prohibitive and they last a long time too. You will find as your eye gets better you will need them less and less. I am surprised more knife makers don't know about them or use them.
