Abstract

Steel is alloyed with the following elements in the chemical composition C, Si, Mn and A1 and has pearlite. Is a metallurgical structure And the value obtained by dividing the quantity of Mn in the cementite in pearlite by the unit of measurement% by atom by the amount of Mn in the ferrite in the pearlite according to the unit of measurement% by atom is greater 0 and equal to or below 5.0
