Does stainless steel spark when grinding? Yes, stainless steel does indeed produce sparks during grinding operations. . This repetitive process creates the characteristic dendritic or branching pattern observed in spark testing. . The grinding wheel should have a grain size of 46# or 60# (preferably 60#) and medium hardness 200mm, and the .How to use the spark test: Not sure what material you've got? A spark test can answer your questions. Get out your grinding wheel and use these photographs as a guide. Tungsten carbide, has a rockwell hardness of 88 to 90, second only to diamonds; its specific gravity is 16, almost as heavy as gold, twice as heavy as high speed steel. Beside spark testing and chemical spot checking, we also used eddy current testing to differentiate 4140 and 4340.
