Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If age-hardened to final properties
Heat treatment beyond basic annealing may constitute finishing, moving to 7222.30 finished stainless bars.
If rectangular cross section instead of circular
7218.99.0030 covers other (non-circular) stainless semi-finished under 232 cm².
