| Standard rail steel has a predominantly pearlitic structure with a nearly eutectoid content of carbon and fine plates of pearlitic cementite. |
| Ferritic and pearlitic malleable irons are both produced by annealing white iron of controlled composition. |
| With pearlitic microstructure, austenite formation occurs in two stages. |
| The microstructure in this case was pearlitic with some steadite and free carbide but no free ferrite. |
| Fully pearlitic malleable iron may be surface hardened by either induction heating and quenching or flame heating and quenching. |
| In testing against another CBN material where pearlitic cast iron brake discs were finished, the CBN200 machined 12,000 parts per edge vs. |
