Different between Ferrous Materials

The different Between ferrous Materials test result are as follows:

1. The spark patterns of ordinary structural steels and unalloyed tool steel are determined by the carbon content as the carbon content increases. The frequency of the C explosions increases accompanied by lateral branching of the ray pattern.
2. The sparking pattern of alloyed tool steels is altered by changes the in alloying components. Manganese alloyed tool steels produce bright bulges in the main beam. Molybdenum alloyed tool steels produce ray ends with lance lips chromium tungsten alloyed tool steels produce discontinuous beams with tongue shapped end sparks high-speed steels produce broken rays of sparks, practically without C explosion.

The test is best carried out by grinding a comparison steel of known composition along with.
