Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy steel, not qualifying as stainless
Chemical composition threshold separates stainless (10.5%+ Cr) from alloy steel tubes.
If imported for pump/motor housing rather than drilling
End-use determines drilling-specific 7304 vs general industrial tube 7306.
If as pump shafts or similar assembled components
Machined into finished pump parts shifts from raw pipe to machinery parts.
