JME1149 Posted June 12, 2015 Share Posted June 12, 2015 I was thinking about something this morning and can't convince myself which answer is correct, so I'm turning to the experts for opinions. When making a billet, let's say I start with a simple 5 layer stack; low carbon / nickel / high carbon / nickel / low carbon. When you cut and stack, or fold, or whatever, for the next step, does it make a ten layer billet? Or is it a nine layer because the two stacked surfaces being the same material would essentially be one thicker layer of the same material? To clarify, is it LC/NI/HC/NI/LC/NI/HC/NI/LC, or is that center LC layer considered two LC's? Link to comment Share on other sites More sharing options...
basher Posted June 12, 2015 Share Posted June 12, 2015 Its up to you.........call it what you want. its easier to just double so I do that. Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 12, 2015 Share Posted June 12, 2015 Both methods are used, people who use the 2N-1 count say that since you have the same material doubled onto your self it is just a double thick layer. The 2N group say that then making a billet from cable will show no patterns as it's all the same material---but it does show a pattern and so 2N should also. Then there are the ones that say layer counts and folds are really fairly meaningless without a whole lot of details, (I have 1000 layers in a piece 2 meters thick---I have 100 layers in a piece 1 mm thick which has the higher layer count?)

Steve Sells Posted June 12, 2015 Share Posted June 12, 2015 dont matter as long as your counting for your benefit is consistent you will be able to repeat what you did later. in the end your count will never be 100% correct due to scale and grinding losing layers anyway. The only way to know for sure is to cut it in half and count under a microscope Link to comment Share on other sites More sharing options...

Most times though I tripple or quadruple stack, but you get the idea. It's all an aproximation. Link to comment Share on other sites More sharing options...
Maurice Gedney Posted July 30, 2015 Share Posted July 30, 2015 it is 2LCs as there is a weld in between the join and so it is easier coconut by doubles as then you know how many welds their are. Link to comment Share on other sites More sharing options...

j.w.s. Posted July 30, 2015 Share Posted July 30, 2015 And let's not even think about all the layers that get removed during cleaning.. once you get above 100, a slight hesitation with the grinder could take 5 or more layers with it. J Link to comment Share on other sites More sharing options...
