lyuv Posted October 7, 2017 Share Posted October 7, 2017 Burning steel is nothing new to me. Usualy the piece is "eaten" at the corner or the edge. I guess because the thinner part heats faster and is more exposed to oxigen. But this time it was different - The piece was cut through, in the middle. How does that happen? The piece is a damascus billet in the work. 15n20 and 125sc (very high carbon steel). Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 8, 2017 Share Posted October 8, 2017 I I have a build up of clinker in the fire and start putting more air into it to get the temp up I have sometimes seem to have reinvented the cutting torch where a hole in the clinker allows a plume of oxygen rich air to enter the fire, Quote Link to comment Share on other sites More sharing options...

So it makes perfect sence there where air (and oxigen) jets. Thanks! Quote Link to comment Share on other sites More sharing options...
