Old N Rusty Posted April 24, 2011 Share Posted April 24, 2011 Mithrael? spark how? a bench grinder or a hand wheel? Most 300 series stainless spark very little some long reddish non bursting sparks, is all you can expect to see. Quote Link to comment Share on other sites More sharing options...

thingmaker3 Posted April 28, 2011 Share Posted April 28, 2011 Metal. It is absolutely, definately metal. Does a magnet stick to it at room temperature? Does a magnet stick to it after you've packed it in dry ice? Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted April 28, 2011 Share Posted April 28, 2011 Dont forget 200 series SS. Not all stainless is non magnetic, nor have a high carbon. Testing by sparks can only help you guess so much, as I always say, ya never know about found metals. Hammer away and have fun with it.

don't tread on me Posted April 29, 2011 Author Share Posted April 29, 2011 I got it to spark I just had to use more RPM's and it is non magnetic. Quote Link to comment Share on other sites More sharing options...
thingmaker3 Posted May 5, 2011 Share Posted May 5, 2011 I got it to spark I just had to use more RPM's and it is non magnetic. Two tests remaining: first, put it in a strong magnetic field and see if it can be temporarily magnetized. If so, you've got ferritic stainless. Next, dunk it in liquid nitrogen & see if a magnet sticks to it when it is really cold. If so, and if you've determined it is not ferritic, you'ved got austenitic stainless. The more important question, of course, is "whatcha gonna make from it?" Quote Link to comment Share on other sites More sharing options...
