Hard Alloy Grades and Applications for Cutting Tools
YW1 exhibits good red hardness and can withstand moderate impact loads, making it a versatile alloy. It is suitable for machining difficult-to-cut materials such as heat-resistant steels, high-manganese steels, and stainless steels, as well as for machining ordinary steels and cast irons.
YW2 exhibits wear resistance second only to YW1; however, it boasts higher service strength and can withstand substantial impact loads, making it suitable for roughing and semi-finishing operations on heat-resistant steels, high-manganese steels, stainless steels, and alloy steels, as well as on ordinary steels and cast steels.
YT30 exhibits higher wear resistance and allowable cutting speeds than YT15, but its strength and impact toughness are relatively poor. It is suitable for finish machining of carbon steels and alloy steels, such as precision turning, precision boring, and precision reaming of small-diameter workpieces.
YT15 exhibits superior wear resistance compared with YT15 alloy, but its impact toughness is lower than that of YT5. It is suitable for semi-finishing or finishing operations on medium- to small-depth cuts in steel, cast steel, and alloy steel.
YT14 exhibits high strength, excellent impact resistance, and good seismic performance, second only to the YT5 alloy; however, its wear resistance is superior to that of YT5. It is suitable for rough turning and rough milling of carbon steels and alloy steels under continuous cutting conditions, as well as for semi-finish and finish turning under intermittent cutting conditions.
YT5 exhibits high strength, excellent impact resistance, and good seismic performance in tungsten-cobalt-titanium alloys, but its wear resistance is relatively poor. It is suitable for rough turning, rough planing, and semi-finish planing of carbon steels and alloy steels, including forgings, stamped parts, and cast-iron surfaces, under intermittent cutting conditions.
YG3X exhibits excellent wear resistance but relatively poor impact toughness among tungsten-cobalt-titanium alloys, making it suitable for high-speed finish machining of cast iron, non-ferrous metals and their alloys, quenched and tempered steels, and small-section alloy steels.
YG3 has wear resistance second only to YG3X; it is relatively sensitive to impact and vibration, making it suitable for finish and semi-finish turning of cast iron, non-ferrous metals and their alloys during continuous cutting, as well as for thread turning and reaming.
YG6A is a fine-grained cemented carbide with excellent wear resistance, suitable for the semi-finishing of chilled cast iron, non-ferrous metals and their alloys, as well as for the semi-finishing and finishing of high-speed tool steels and alloy steels.
YG6X is a fine-grained tungsten carbide alloy with higher wear resistance than YG6 and comparable strength. It is suitable for machining chilled alloy cast iron and heat-resistant alloy steels, as well as for the finish machining of ordinary cast iron.
YG6 exhibits higher wear resistance than YG3, but lower wear resistance than YG3X; it also offers better impact and vibration resistance than YG3X. It is suitable for semi-finishing and finishing operations on cast iron, non-ferrous metals and alloys, and non-metallic materials at moderate cutting speeds.
YG8 exhibits high strength, excellent impact resistance, and superior seismic performance compared with YG6; however, its wear resistance and permissible cutting speed are lower. It is suitable for low-speed rough machining of cast iron, non-ferrous metals and alloys, and non-metallic materials.
YG8N is suitable for rough machining of cast iron and non-ferrous metals, as well as for finish and semi-finish machining of stainless steel.
YD201 is suitable for semi-finishing and roughing of cast iron and light alloys, and can also be used for milling operations on cast iron and low-alloy steels.
