Tungsten Carbide Bar

Tungsten carbide bars from my customer's inquiry as below:

Now this order have been finished about 1 thousand pieces. The order quantity is 6 thousands pieces, we will finished it before July.
We have send 450 pieces to our customer and he was very like them.
Hope we can finished these products successfully and have a continued cooperation with my custoemr.

Below was our tungsten carbide balls property for your reference.

Class	Grade	Chemical Composition				Physical-Mechanical Property			Performance characteristic	Orientation for Property Increasing
		WC	Co	Ni	Others	Density g/cm³	Hardness （HRA）	T.R.S. N/mm²
WC + Co	YG6	Balance	6			14.6-15.0	91	1600	The hardest and most wear resistant. Lower toughness than YG8. Used in ball valves that is high abrasion and high impact resistance.	↑ Abrasive Resistance Toughness ↓
	YG8	Balance	8			14.4-14.8	89	1800	Higher hardness and wear resistant. Better toughness than YG6. Have a well shock resistance, used in ball valves.
	YG6X	Balance	6		A Little	14.6-15.0	92	1450	Submicron carbide, higher hardness and wear resistance than YG6, lower toughness than YG8. Used in ball valves that is high abrasion and high impact resistance.
WC + Ni (Cr)	YN6	Balance		6	A Little	14.5-14.9	90	1450	Higher hardness and wear resistance and corrosion resistant. Used in ball valves where high temperature is required.	↑ Abrasive Resistance Toughness ↓
	YN8	Balance		8	A Little	14.4-14.8	88	1650	Higher hardness and wear resistance. Used in ball valves where shock resistance and corrosion are required.
	YN12	Balance		12	A Little	14.0-14.4	86	1800	Higher toughness for impact load .Use in ball valves where better shock and impact are required.
