Abstract: The creep tests of microalloyed steels h300lad and h380lad are studied in this paper. In order to test the properties of these steels, tensile and creep tests were carried out in the temperature range of 200 – 500 ° C. Microscopic and Submicroscopic Observations were made on the torn samples. The microalloyed steel was compared with the alloy steels c16e and 16mo3 used at the same temperature. The experimental results emphasize the possibility of the application of microalloyed steel in the specified temperature range.
