Hot-Rolled 100Cr6 Ball-Bearing Steel Sheet from Mexico

Flat-rolled hot-rolled sheet of 100Cr6 (EN 31) ball-bearing steel, 280 mm width by 4.5 mm thickness, in straight lengths not in coils. Meets HTS 7226.91.25.30 criteria for alloy tool steel of width <300 mm, not further worked, with ball-bearing composition including 0.95-1.13% carbon and 1.25-1.65% chromium. Essential material for bearing races and rolling elements.

Import Tips

Provide detailed chemical analysis proving compliance with ball-bearing steel note (h); CBP often requests verification for 52100/100Cr6 equivalents

Measure and document exact width before rolling to confirm <300 mm; over-width shifts to broader 'other' subheadings

Avoid rust/discoloration claims at entry per Chapter 72 note—no duty allowance for pre-entry surface oxidation
