AISI 52100 Cold-Rolled Ball Bearing Steel Strip from Canada
Flat-rolled strip of AISI 52100 alloy steel, cold-rolled to precise thickness under 3mm and width less than 300mm, specifically formulated for ball bearing production with controlled carbon (0.95-1.13%), chromium (1.25-1.65%), and low impurities. It falls under HTS 7226.92.3030 as not further worked than cold-rolled, of tool steel meeting ball-bearing steel definition, and width under 300mm. This high-purity steel ensures minimal defects in bearing raceways and rolling elements.

Import Tips
• Provide mill test certificate confirming ball-bearing steel composition per US Note (h) with exact elemental analysis including C 0.95-1.13%, Cr 1.25-1.65%
• Verify cold-rolled condition only - no polishing, coating, or heat treatment beyond rolling qualifies as 'further worked' per Chapter 72 notes
• Measure width precisely before entry; strips over 300mm shift to 7226.92.3050, changing duty rates
