KORLOY Cermet GradesSpecial FeaturesKORLOY cermet is a kind of carbonitride type cermet which has ultra finemicro structure by adding TiN, TiCN powders as additives. It has superiorthermal shock resistance and optimal wear resistance and toughness asper cutting condition, as well.Special AdvantagesCermet, using TiCN as main component, is harder than cementedcarbide and has lower affinity with Ferrous work piece at hightemperature , thus cermet have special advantage as below,Comparing with Un-Coated Carbide1. Since cermet has superior wear resistance and cratering resistance, higherspeed cutting is available.2. Since cermet has low affinity with ferrous work piece, from low to highspeed cutting is available.3. Low affinity with work piece provides excellent surface finish.4. Exceptional tool life and cutting performance can be acquired at high speedfinishing.Comparing with Coated Carbide1. Suitable for light cutting(finishing).2. Better wear resistance and surface finish can be acquired at the samecutting condition.Microstructure of CermetGuide of Grade SelectionTurningWorkpiece Coating 1st ChoiceCutting Speed(m/min)(sfm)ISOApplication RangeFinishingCC105CC115230(150 ~ 300) 750(490 ~ 980)P01CC105SteelLight tomediumcuttingCN100CT10CN2000200(150 ~ 280) 660(490 ~ 920)200(130 ~ 250) 660(430 ~ 820)200(150 ~ 250) 660(500 ~ 830)P10P20CN100 CC115CT10CN2000CC105, CC115 is Coated Cermet Grades.MillingWorkpiece Coating 1st ChoiceCutting Speed(m/min)(sfm)ISOApplication RangeFinishingCN20230(150 ~ 300) 760(500 ~ 990)P01CN20SteelLight tomediumcuttingCN30200(150 ~ 250) 660(500 ~ 820)P10P20CN307
