Molecular formula : MW : CAS :
nature : steel heated to slightly lower or slightly higher than the eutectoid than steel or steel eutectoid temperature, then slowly cooling down. The objective is to make the Pearly intimate Flake cementite and first eutectoid cementite turned into a spherulitic, evenly distributed in ferrite matrix (such as the Organization of pearlite ball). Such organizations have had high carbon steel and low hardness). It is the types of carbon steel and high-carbon steel low hardness, good cutting, cold deformation huge. Right tool steel, this organization is the best pre-quenching of the original organizations.
