Products classified under HTS 7228.30.20.00
AISI 52100 Hot-Rolled Ball-Bearing Steel Round Bar
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.
Ball-Bearing Steel Hot-Extruded Hexagonal Rod
Hot-extruded hexagonal rod of ball-bearing steel compliant with US Note (h), featuring controlled low impurity levels for superior fatigue resistance in rolling bearings. Not further worked than extrusion, it fits HTS 7228.30.2000 as other rods of ball-bearing tool steel. Used primarily for manufacturing bearing components requiring dimensional stability under load.
SUJ2 Hot-Rolled Ball-Bearing Steel Square Bar
SUJ2 (Japanese equivalent to AISI 52100) hot-rolled square bar meeting ball-bearing steel specifications in HTS Chapter 72 note (h), ideal for precision bearing rings. Delivered not further worked than hot-rolling, properly classified under 7228.30.2000. Offers excellent surface quality and minimal inclusions for high-cycle bearing applications.
100Cr6 Ball-Bearing Steel Hot-Drawn Flat Bar
100Cr6 (EN standard) hot-drawn flat bar of ball-bearing steel per US Note (h), with precise 1.0% carbon and 1.5% chromium for roller bearing applications. Not further worked, classifying under HTS 7228.30.2000 as alloy tool steel bars. Provides consistent hardness after heat treatment for heavy-duty bearings.
GCr15 Hot-Rolled Ball-Bearing Steel Rod
Chinese GCr15 grade hot-rolled rod equivalent to AISI 52100, certified to ball-bearing steel specs in HTS note (h) with controlled manganese and silicon. Used for bearing balls and races, imported not further worked under 7228.30.2000. High purity levels ensure long bearing life under high speeds.
