CEMENTATION PROCESS


THE PURE WROUGHT IRON BARS ARE ARRANGED IN THE FORMATION BETWEEN THE LAYER POWDERED CHARCOAL AND MAINTAINED AT HIGHER TEMPERATURE (1500’C) FOR 5 TO 15 DAYS DEPENDING UPON  THE QUALITY OF STEEL REQUIRED . THE WROUGHT IRON GETS COVERED WITH BLISTER DUE TO COMBINATION OF CARBON AND THUS STEEL SO PRODUCED IS TERMED AS “BLISTER STEEL”. BLISTER STEEL HAS FISSURES AND CAVITY AND ALSO ITS STRUCTURE IS NOT HOMOGENEOUS . IT MAY BE EMPLOYED FOR MACHINED PARTS AND FACING HAMMER BUT LESS SUITABLE FOR EDGE TOOL.
