Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If forged rather than cast
Forged iron/steel rough parts have separate cast-iron exclusion.
If general cast articles
Rings not principally gas turbine parts classify as other iron/steel castings.
If sold as pulley/drive component
Flywheels/pulleys of cast iron separate even if turbine-related.
