Products classified under HTS 8455.90.80.00
Forged Steel Work Rolls for Hot Rolling Mills
These are precision-forged steel rolls used as the primary contact rolls in hot strip rolling mills to shape metal slabs into sheets. They fall under HTS 8455.90.80.00 as other parts of metal-rolling mills, specifically work rolls thereof, designed for high-temperature deformation of metals.
Backup Rolls for Cold Rolling Mills
Large diameter backup rolls provide structural support behind work rolls in cold rolling mills for precise thickness reduction of steel strips. Classified under HTS 8455.90.80.00 as other parts of metal-rolling mills, these are essential for maintaining roll alignment under high pressure.
Chilled Cast Iron Guide Rolls
Chilled cast iron rolls used to guide and align steel strips entering rolling mills, preventing edge damage. These fall under HTS 8455.90.80.00 as other parts of metal-rolling mills, distinct from shaping work rolls.
Tungsten Carbide Surfaced Leveling Rolls
Specialized leveling rolls with tungsten carbide coating for flatness correction in rolling mill entry sections. Classified in HTS 8455.90.80.00 as other coated parts for metal-rolling mills.
Segmented Roll Assemblies for Wide Strip Mills
