A method and apparatus for determining the critical temperature at which Bainite is formed from a low carbon steel, and for forming a steel material with a predetermined percentage of Bainite. The temperature of low carbon steel is raised to a temperature above the critical temperature at which Bainite is formed. The temperature is then raised to the critical temperature and maintained at that level until a predetermined percent of the steel microstructure has changed to Bainite. A novel chain pump is disclosed for maintaining the steel at a selected temperature plateau.
