AISI 52100 Cold-Rolled Ball-Bearing Steel Sheet from Canada
Flat-rolled alloy steel sheet of AISI 52100 grade, cold-rolled to precise thickness between 0.5-3mm and width over 600mm, specifically formulated for ball-bearing applications with 0.95-1.13% carbon and 1.25-1.65% chromium per Chapter 72 note (h). Not further worked beyond cold-rolling, classified under HTS 7225.50.11.30 as tool steel of ball-bearing quality. Used primarily in manufacturing high-precision bearing components requiring superior hardness and fatigue resistance.

Import Tips
• Provide mill test certificate confirming ball-bearing steel composition per US Note (h) (e.g
• 0.95-1.13% C, 1.25-1.65% Cr) at time of entry
• Verify product meets 'not further worked than cold-rolled' criteria - no polishing, coating, or cladding allowed under this subheading
• Ensure accurate width measurement (>600mm) and distinguish from hot-rolled products to avoid misclassification
