RB370 Steel

Steel name: RB370
Diagram No.: 4975
Type of diagram: CCT
Chemical composition in weight %: No data
Steel group: Bainitic rail steels
Note: Austenitizing temperature: 950 C/20 min. The CCT diagram of the low carbon Mn-Cr-Mo-V bainitic rail steel. Shaded area contains the range of air cooling curves, realized on a cross section of UIC60 rail. Fig. presents CCT (Continuous Cooling Transformations) diagram of new bainitic steel for rail tracks with trade name RB370. It is low carbon nickel-free steel Mn-Cr-Mo-V. Shaded area on CCT diagram contains experimentally determined, range of air cooling curves, realized on a cross section of UIC60 rail. Observing the position of the range, in relation to bainitic transformation, one may be sure that within entire cross section of such rail, air cooled after rolling, bainite (lower bainite) will be formed or developed.
