What is Spheroidsing
Spheroidsing is the method that applies more to the hypereutectoid steels (above 0,8% C). The process includes heating the metal to between 600oC and 650oC and holding it at the selected temperature for a period of time the cementite alters from a lamella formation to a formation based on an alpha ferrite matrix with particles of spheroidal cementite (Fe3C) are fixed. This resulting steel has better ductility and toughness compared to the original steel with decreased hardness and strength.
