Competence analysis with first-class laboratory equipment to the scanning electron microscope for the evaluation of cuts in the heat treatment. Target less consumption-resource-saving, clean, avoid water in the production steps. Hardening, annealing, tempering and annealing. Competence analysis, process monitoring, quench monitoring, KSS analytics and monitoring. Accompanying sampling and analysis time set budget position for changing the bath. Oils do not last forever. Tags acidity increase, scale entry, water entry, etc. In ZTU note that needs to be partially cooled to minimize the delay.
