Abstract
Paraffin wax (sulfur and phosphorous free)used as carburizer material for low carbon steels(Steel20, Steel3, and Steel 20x) instead of kerosene. Results show 1) Carburized layer by wax is more depth than in case of kerosene for all the three types of steel, e.g. for steel 20x the depths are 1.336 0.001 and 0.98 0.15 mm respectively 2) More homogenized carburized layer by wax than by kerosene 3) Higher hardness carburized layer by wax than by kerosene, for steel 20x (61.5 and 59.5 Rockwell Respectively) 4) Carburized layer by wax contains 0.017 % sulfur and 0.98 % carbon while 0.022 % sulfur and 0.93 % carbon by kerosene 5) No sludge materials residue remain on the steel treated surface as in case of using kerosene 6) Under the same conditions (temperature, pressure, and volume) wax shows shorter time than kerosene to get the same depth of carburized layer 7) Wax is more save than kerosene as poisonous and fire hazard material 8) No corrosion effects on the furnace and its heaters in case of using wax than with kerosene (kerosene contains 0.2 % sulfur).
