GCr15 Hot-Rolled Ball-Bearing Alloy Steel Plate
Hot-rolled plate of GCr15 Chinese-standard ball-bearing steel, 295 mm wide x 6 mm thick, used for precision bearing components. Fits HTS 7226.91.25.30 as other alloy tool steel, hot-rolled only, width under 300 mm, matching U.S. ball-bearing steel elemental requirements (low P/S, specific C/Cr). High hardness after heat treatment for roller bearings.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other alloy steel not tool steel
Non-tool alloy steel flat-rolled products <600mm classify under 7224, excluding specific tool/ball-bearing compositions.
If high-strength steel per note (a)
Flat-rolled products meeting high-strength yield point criteria (e.g., ≥355 MPa for ≥3mm thick) have dedicated subheadings.
If chipper knife steel per note (f)
Specific chipper knife alloy composition (high Cr/Mo, narrow C range) uses separate tool steel subheading.
