Product name:stainless steel polished sphere water fountain/feature
Properties
Corrosion Resistance: AISI 316 > 304 > 302.
Hardenability: The above stainless steel are not hardenable by heat treatment. Some work-hardening takes place on balls during cold-forging.
Magnetism: AISI 304 and aisi 302 are slightly magnetic and AISI 316 is non magnetic. However, in the manufacture of steel balls and media during cold forging / heading, slight magnetism is induced in all the stainless steel types.
Passivation: The stainless steel balls are passivated after final polish. Carryover iron and other contaminants are removed and a surface film prevents atmospheric and water corrosion.
