QT Steel


QT Steel software has been developed to predict the heat treatment response of through hardened, carbon and alloy steels in terms of micro structure and mechanical properties. The software has been developed by ITA Ltd a company (http://www.ita-tech.cz) which MSL work in close partnership with. The software uses FEM to calculate cooling rates of components and special algorithms to predict the continuous cooling transformations.

QT Steel allows the selection of appropriate steels and the optimized heat treatment for new and existing components.  It can therefore play an important part in the economic analysis of manufacturing routes and the selection of the lowest cost steel.

QT Steel will provide data on the following:

  • Decomposition diagram of steel with the given chemical composition displayed.
  • Predicts and displays the cooling curve calculation for a range of materials in varying shapes (round or flat bars, cylinder, ring, pipe) and sizes. There are different cooling conditions stored within the QT Steel program (cooling media database), thus allowing the user to select the appropriate cooling media to complete the cooling curve calculation.
  • Import information from about general 2D-solids which have been calculated in FEM packages (FLUX, FormFEM)
  • Calculates the microstructure of the steel (the content as a % of Ferrite, Pearlite, Bainite and Martensite)
  • Mechanical properties of the steel (HV, HB, HRC hardness, yield strength, tensile strength) after quenching and subsequent tempering/annealing for a given cooling curve. This information can also be gathered across the heat treated components cross section or in its areas under the surface
  • Calculation of mechanical properties progression after hardening (tempering/annealing), depending on the depth under the heat treated body surface

The following steel groups are supported by the QT Steel software:

  • Carbon medium alloyed steels – with a carbon content range of 0.06% to 0.5% with alloying elements total amount to 10%
  • Low carbon micro alloyed steels – with a carbon content range of 0.06% to 0.4% on condition that Nb + Ti > 0
  • Low alloyed tool steels – with a carbon content ranging from 0.6% to 1.8%. Alloying elements must amount up to 5% if the carbon content is less than 1.2% or the alloying elements should amount up to 3% if the carbon content is more than 1.2%
