Metal Alloys Wear and Properties

A metallurgical route to produce S700MC/Grade100 steel on a hot strip mill has been developed at ArcelorMittal Europe, based on laboratory simulations and industrial trials. The importance of ThermoMechanically Controlled Processing (TMCP) has been illustrated, mainly to optimize the low temperature toughness. Furthermore, it has been shown that the optimum combination of strength and low temperature toughness can be found through optimization of the transformation and the precipitation. The concept developed shows a good robustness against typical industrial process variations.The steel shows a good weldability using typical MAG welding parameters, without loss in strength and a good toughness. The high cycle fatigue performance of the steel is very good.
