Steels with Chromium content between 10–18%, Carbon up to 2% and with the addition of other elements.

In order to improve both mechanical properties and corrosion resistance, they are heated to an appropriate temperature, 950°-1050°C, followed by suitable quenching and tempering.

Martensitic steels are ferromagnetic.
