the_sandy_creek_forge Posted September 16, 2006 Share Posted September 16, 2006 Hi all, I happened upon an old run of the mill toaster oven at a garage sale today, and then happened to notice that the temperature setting went too 500 degrees farenheit and then went about another 25-30 degrees (like circle degrees not temperature degrees) around the circle to a MAX setting. Hm...five dollars....So once it got home I plugged it in and borrowed a lazer thermometer gun, sure enough the thing , on MAX , reaches around 550 degrees. So now that i've found a makeshift heat treating oven to draw temper with, I wonder how long, per inch , steel needs to stay at a given temperature to heat through. I believe I read in one of my books that it was one hour per inch , but now i can't find that passage. Any ideas on this?? Thanx all -Aaron @ The SCF Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted September 28, 2006 Share Posted September 28, 2006 You want to make sure that the center of the piece comes up to full temperature; however it's the thermal cycling that does most of the work. You will do better to have it come up to full temp 3 times than just once and then maintain it for a long while. Thomas Quote Link to comment Share on other sites More sharing options...
