Home Bearing News NSK Introduces New ES1 Stainless Bearing Steel NSK Introduces New ES1 Stainless Bearing Steel Lately, Shanghai Bearing Supplies is informed of the news as follows: NSK Ltd. announced it is commercializing its newest stainless steel,ES1, suited for use manufacturing bearings that will seeinstallation in applications where corrosion resistance isparamount. The most common stainless steel used to manufacture bearings is440C. However, 440C has a key limitation, which is that is hasconcentrated chromium coarse eutectic carbide inclusions. Thoseinclusions lead to three key areas of weakness. First, thoseinclusions make it virtually impossible to get the best finish onthe bearing races, so 440C bearings normally run loud, rough, andcan run hot. Second, under load, cracks initiating at theseinclusions are what usually lead to a 440C bearing failure throughflaking and spalling. And third, those inclusions make 440C lesscorrosion resistant because the chromium is lost in the martensiticmatrix. ES1, originally discussed by NSK in 2000, is a new martensiticstainless that NSK developed with an eye toward carbide size andcomparable Rc hardness to 52100 bearing steel. ES1 is essentially440C with higher nitrogen and lower carbon and chromium. Reducingthe chromium and carbon is what helps eliminate the eutecticinclusions. Alloying the nitrogen is what provides superiorcorrosion resistance. NSK is doubtlessly one of the world leading bearing manufacturerswhich devote themselves to researching higher technology andproviding higher quality products.
