7226.91.25.30/AISI 52100 Hot-Rolled Ball-Bearing Steel Strip/China

AISI 52100 Hot-Rolled Ball-Bearing Steel Strip from China

Hot-rolled flat-rolled strip of AISI 52100 alloy steel, measuring 250 mm wide and 5 mm thick, not further worked beyond hot-rolling. Classified under HTS 7226.91.25.30 as flat-rolled product of other alloy steel, width under 300 mm, of ball-bearing steel per U.S. note (h) with specific carbon (0.95-1.13%), chromium (1.25-1.65%), and low sulfur/phosphorus content. Used primarily for manufacturing high-precision ball bearings.

Import Tips

• Certify at entry that steel meets U.S. note (h) ball-bearing steel specs (e.g

• 0.95-1.13% C, 1.25-1.65% Cr, ≤0.03% S/P) with mill test certificates

• Verify width <300 mm and hot-rolled only (no cold-rolling, polishing, or coatings) to avoid reclassification as further worked

• Include heat analysis reports; common pitfall is mislabeling tool steel variants not meeting exact ball-bearing elemental limits
