The paper deals with heat affection of selected armoured ultra-high strength steels after their cutting by plasma and laser and their welding with using MAG welding method where critical degradation of mechanical properties could occur in heat affected zone after application of these technologies. Armox steels are armoured ultra-high strength martensitic steels with the usage in special technology. The steels are produced in the form of forged semiproducts as sheets and plates. These sheets are cut and most commonly welded in a way to made the final product. Experimental samples made of Armox 500 steel with using of aforesaid thermal based technologies are studied in the paper to evaluate selected heat affected zone parameters.

Keywords: high strength steel, martensite, tempering, armoured steel, hardness, microstructure
