Chemical component:

Material   Feature

AISI 304    austenitic, corrosion resistance,   slightly magnetic, however annealing, can makes it non - magnetic

AISI 201    Acid and alkali resistance, high   density, polish no bubbles, pinhole-free, best for decoration and industry.

AISI 316    non-magnetic, good corrosion resistance even   when exposed to marine atmosphere and sulfuric acid
