Hardenability aftereffect of boron in metal isrelated to your level of boron, carbon content plus the austenitizingtemperature out of metal. Usually increases while the carbon content increases, therole associated with the boron was progressively lower. Into the most useful austenitizing temperature,the hardenability aftereffect of boron is the best. The studies reveal your massfraction associated with the boron in metal should really be more than 0010, quite down or excessive cannot make the very best effects.
