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. |
Austenitic Stainless Steel Balls The largest category of stainless steel, accounting for about 70% of all production. The austenitic class offers the most resistance to corrosion in the stainless group because of its substantial nickel content (8%) and higher levels of chromium(18%). Austenitic stainless steels are hardened and strengthened through cold working (changing the structure and shape of steel by applying stress at low temperature); they are unhardenable by heat treatment. Ductility (ability to change shape without fracture) is exceptional for the austenitic stainless steels. |
