2. Diameter: from 19mm to 3000mm, thickness from 0.3mm to 8mm 3. Grade: G10-G1000.4. Corrosion Resistance: AISI 316 > 304 > 302.
6. Feature: Processing, light smooth, delicate and beautiful, type, many styles, variety complete, no holes. Seamless, no weld mark.
7. Application: For indoor & outdoor decoration. 304 stainless steel ball can be used for nail polish , sprayer , scent bottle ,lipstick , aerospace , electric elements , Construction Materials and so on.
Features:
A. Hardenability: The above stainless steel are not hardenable by heat treatment. Some work-hardening takes place on balls during cold-forging.
B. 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.
C. 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.
