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.

Manufacture process of steel balls
Step 1 HeadingBalls blanks are cold headed from rolls of wire.
Step 2 FlashingRolling balls between two hard alloy plates to removes the slight band
and small protrusions.
Step 3 Heat treatHeating balls to a high temperature in furnace and quenching balls in a liquid bath.
Step 4 Rough grindRolling 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 CleaningThe 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 PackagingThe balls are packaged in accordance with customer specifications for shipping.
