·                            Applications: 304 stainless steel ball is the most widely used market, a ball can be used for medical equipment, chemicals, aviation, aerospace, plastic hardware: perfume bottles, sprayers, valves, nail polish, motors, switches, electric irons, washing machines , refrigerator, air conditioning, medicine, auto parts, bearings, instruments, baby bottles.

·                            Characteristics: typical of austenitic steel, generally non-magnetic, but after the ball through the light with magnetic, removable magnetic, HRC ≤ 26. Has good anti-rust, corrosion resistance.

·                            Comparison: 304HC stainless steel ball stainless steel ball more than 304 soft and easier to process, and 304L stainless steel ball than the above two are more rust and corrosion resistance, easy welding, polishing of good, better suited to the surface demanding industry.
