Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If austenitic with <8% Ni like 304
Standard 300-series nickel levels determine specific suffixes.
If used in refractory furnace linings
End-use as ceramic refractory material changes chapter.
If cold-drawn and ground finish
Surface working beyond hot-rolled moves to 'further worked' categories.

Import Tips & Compliance
• 310 series needs high-temp oxidation test documentation
• Confirm not qualifying as 'heat-resisting steel' per US Note (g) <0.3%C
• Scale removal treatments may count as 'further worked'
