Phase Transformation Data

Phase transformation data at a glance

With the phase transformation data, StahlDat SX contains over 400 diagrams for different grades, short names and chemical compositions at variable temperatures.

Data basis

The time-temperature transformation (TTT) and continuous cooling transformation (CCT) diagrams are based on the atlas on heat treatment of the VDEh.

How to find suitable TTT/CCT data

With StahlDat SX phase transformation data, finding suitable data is particularly easy:

  • Search for phase composition at different austenitisation temperatures
  • Providing literature for the corresponding TTT and CCT diagrams
  • Tabular comparison of different diagrams
