what was not clear about that in the heat treating sticky post? you didnt specify

what was rude? you just said what about the anvil, and that wasnt really a clear question in there, It seems you are the one getting frogy

A36 isnt an alloy its a structural spec, so you just told us that you used mystery metal and wonder why the etch didnt work right, correct?

what burner do you have? what pressure are you running? you didnt even state what fuel your using or how it is supplied or even how it gets air, the world is a big place, not all of us have the same set up

his Ebay add also makes the interesting claim of *Also can be used for jewelry making, smelting gold, silver, or lead, or any other high heat craft projects. so it must be great huh

one would assume his Highness already has her approval, why else would he assume the title of King ? its very presumptuous on world wide forum otherwise

apprentices needed work too

from page 134, Intro to knifemaking: There are no high and low carbon content layers to pattern welded steels. Some layers may be softer in the end but that is only due to the nature of that layers alloys. Not all elements migrate as fast as carbon does. According to metallurgist Thomas Nizolek: When we forge weld steels together, the carbon content in any layer of steel will equalize with that of the surrounding layers of steel very quickly. In Pennsylvanian, February 2009, Laboratory testing was made on a forge welded billet made from 4 alternating bars of W2 and 203E. This examination was done with an electron microscope. In the four layer sample it is evident, based on the pearlite gradient between the layers, that extensive carbon diffusion occurred after the first weld course. Drawn out and folded, the eight-layer sample showed that the pearlite concentration has almost equalized, however ferrite still decorates the prior-austenitic grain boundaries in the 203E layer. By the time the material has reached 16 layers, the carbon content of the sample appears to be uniform. This appears to prove that carbon migration is happening much faster than most smiths had thought in years past. This means that the patterns we have in a billet made from using only simple carbon steels, must be coming from the other alloy differences, and not from the carbon as we use to think. Getting a usable blade means paying attention to our steel's alloy content, which includes the amount of carbon. If the carbon content is too low it will not harden. So a 1095 and 1005 mix will not result in a very hard blade, partially due to carbon migration, because using equal parts of 1095 and 1005 will result in the equivalent of about 1045 in the finished billet. The simple math says 0.50 carbon, but remember to account for the loss of carbon to the atmosphere during welding, as well. Carbon has a stronger attraction to air than to steel. This condition will also cause some of the carbon from the surface layers of our blade to move into the atmosphere. This is another reason to leave the blade thick before hardening. It allows us enough extra material to still have plenty of thickness left after our final grinding, which removes this de-carb layer as we remove the scaling caused by the quenchant.

no photos? this is a "what kind of car to I have, it has 4 wheels" type of thing

ok I stand corrected didnt realize lead boiled so high, but I was only thinking about melting temp because of his budget limits, I have no clue how he will know exact temp otherwise. still I would worry about lead vapors and avoid using lead for heating

not a good idea to use lead to heat up to quenching temp, you need to read different material, there is a long post about heat treating at the top of the page I already wrote so I wont repeat it here.

Most topics in solid fuel section cover both subjects, making it impossible to decide which section they would go into. There is also the question needing to be asked of what purpose would it serve? We currently have enough people that cant understand where to post things, and separating the subjects that belong to both would only confuse them more, not to mention I aint going to spend my time going through the over 80 pages to sort and have to actually read many of the 25,834 unclear titled posts to decide which area they belong in, and no one else would do it, (I just finished sorting out 10 pages 250 threads, and 2,750 posts for another sub section)

I covered the speed of carbon migration in my book, so I wont go into that thesis here again other than to say it isnt because of carbon differences because there isnt any. There are other accidental elements in even the best made steels only in a lab can they make pure steels, and that is where the differences comes from. But I will invite you to explain what gives the different colors in steels
