Prediction of Continuous Cooling Diagrams for the

Quenching and tempering of precision forged components using their forging heat leads to reduced process energy and shortens the usual process chains. To design such a process, neither the isothermal transformation diagrams (TTT) nor the continuous cooling transformation (CCT) diagrams from literature can be used to predict microstructural transformations during quenching since the latter The production standard of EN10083 - steel-plate-sheetThe old clients of BBN steel know well that all our factory supply EN10083-3 50CrMo4 1.7228 quenching and tempering steel plates can meet above chemical composition and mechnical properties standard.
