ARMOX steel is an armoured steel with excellent mechanical properties as well as dense hardness, tensile strength and a high level of toughness. These properties result from specific production processes finished with rolling quenching and tempering. The producer of ARMOX steel recommends their secondary processing (cutting, welding, shaping) at temperatures lower than 200°C due to over tempering and the degradation of mechanical properties in heat affected areas. This paper describes the mechanisms and reasons for this degradation including the simulation of the cooling processes concerning ARMOX 500 steel.
