YG6X

K10

14.8-15.1

≥1540

91

A fine grain grade with better wear resistance and simles as that YG6 grade .Suitable for cutting of chilled and alloyed cast irons and alloyed refractory steels, also suitable for finishing of normal cast irons.

YG6A

K10

14.7-15.1

≥1450

91.5

A fine grain grade with excellent wear resistance and suitable for semi finishing of chilled cast iron, on-ferrous metals and their alloys, but also suitable for semi finishing or finishing of hardened steel and alloy steels.

YG6

K15-K20

14.7-15.1

≥1600

90

With better wear resistance, and suitable for semi fishing and finishing of cast irons, on-ferrous metals and their alloys, on metallic materials at medium cutting speed.

YG8

K20
