AISI 52100 Hot-Rolled Ball-Bearing Steel Round Bar from China
A hot-rolled round bar made from AISI 52100 alloy steel, specifically formulated for ball-bearing applications with 0.95-1.13% carbon, 1.25-1.65% chromium, and low sulfur/phosphorus levels as per HTS Chapter 72 note (h). It is not further worked beyond hot-rolling, classifying it under 7228.30.2000 as other bars and rods of ball-bearing steel. This steel provides high hardness and wear resistance essential for bearing races and rolling elements.

Import Tips
• Provide mill test certificate confirming ball-bearing steel composition per US Note (h) to avoid reclassification; ensure product is truly not further worked (no polishing or coating); watch for alloy content declarations as mislabeling can trigger audits
