Temperature at which eutectic transformation occurs in molten steel. Speaking more metallurgical, this can be described as the austenite phase undergoing an eutectoid transformation to produce ferrite(solution with Iron as its main component) and cementite (iron carbide). For steel this point is at 727¡C (1340.6¡F), when Carbon content is about 0.83%. This is more accurate, metallurgical definition of High Carbon steel, C >= 0.83%, not more widespread marketing definition with 0.5% or more Carbon.
