摘要：A method of processing steel includes carburizing a martensitic stainless steelwork piece to produce a carburized case by utilizing in combination, (i) a composition ofthe martensitic stainless steel work piece, (ii) a preselected carbon concentration in the
carburized case, and (iii) a preselected grain size of the martensitic stainless steel workpiece such that the carburized case predominately forms carbides of composition MC,MC, MCor combinations thereof. The martensitic stainless steel work piece is then heatedto substantially solution the metal carbides. The work piece is then quenched at a coolingrate that is sufficient to avoid substantial precipitation of any carbides during cool downto the martensite start temperature, then given a low temperature temper. In so doing,the carburized case hardened martensitic stainless steel will have balanced mechanical,tribological and corrosion resistance properties for high performance bearing and gearcomponents.
