Technical Information for Brazed Tools KORLOY ultra-fine grades “F-Series” O Features In general, when we compare cemented carbide to high speed steel, cemented carbide has higher hardness but is more brittle than high speed steel. To neutralize the difference, KORLOY has developed an ultra fine cemented carbide grade “F-Series”± (WC size under 0.5wm). It provides improved toughness and plastic deformation resistance against cemented carbide having coarse grain sizes. The main coverage for ultra fine cemented carbide is endmilling of difficult-to-cut materials like high temp alloys Micro structure of “F-Series” FA1 Since it is a grade focused on toughness, it is possible to make endmill, side cutter, gun drill, reamer etc. It has superior quality on toughness and anti built-up edge properties FCC It has been modified from FA1 to increase thermal shock resistance, thus FCC has proper properties to machine stainless steel and hard to machine materials at medium to high speed milling FS1 As a ultra fine grade having high hardness and superior toughness at the same time, it is the 1st recommended grade of KORLOY to make sharp cutting edge to cut difficult-to-cut material O Cutting performance Special features Grade Characteristics ISO classification Wear resistance Toughness Specific Hardness Gravity (HrA) TRS (kgf/mm2) FS1 14.4 92.4 250 Z10 0 FCC 12.6 91.5 250 Z10 0 FA1 14.1 91.2 300 Z20 0 FG2 14.3 92.7 350 Z10 0 Chipping resistance Ultra fine grade Carbide G10 0.96 m ..
