What is SUJ2?		Features		Applications		Hardness
SUJ2 is a high-carbon chromium bearing steel in conformity with JISG4805. Non-metal inclusions,which have a harmful effect on the durability of steel, are minimized by the vacuum degassing method.		High load bearing		Bearings		0.8mm-3mm 63-67 HRC
		Fine surface finish		Ball screws
		Through-hardness and high loacapacity		Automotive (transmission, steering, anti-lock brakes)		3.175mm-30mm 62-67 HRC
		Used in demanding industrial applications		Valves Couplings Locks Slides Conveyers		30.1625mm-104.775mm 61-67 HRC

 

Manufacture process of steel balls
Step 1 Heading		Balls blanks are cold headed from rolls of wire.
Step 2 Flashing		Rolling balls between two hard alloy plates to removes the slight band and small protrusions.
Step 3 Heat treat		Heating balls to a high temperature in furnace and quenching balls in a liquid bath.
Step 4 Rough grind		Rolling balls between the face of a fixed iron plate and a very hard fire-grit grinding wheel. Then rolled the hardened ground balls between two cast iron plates.
Step 5 Cleaning		The final production operation cleans the finished balls and adds a shiny luster.
Step 6 Final           Inspection		Balls are gauged, visually inspected and subjected to other quality tests to insure every customer's specifications are achieved.
Step 7 Packaging		The balls are packaged in accordance with customer specifications for shipping.
