Detailed Introduction
Application areas:
304 stainless steel balls are among the most widely used types of steel balls on the market, suitable for applications in medical devices, the chemical industry, aerospace, and plastic‑metal hardware—such as perfume bottles, sprayers, valves, nail polish containers, electric motors, switches, electric irons, washing machines, refrigerators, air conditioners, pharmaceuticals, automotive parts, bearings, precision instruments, and baby bottles.
Features:
A typical example of austenitic steel is generally non-magnetic, but it becomes magnetic after polishing and can be demagnetized, with a Rockwell hardness (HRC) of ≤26. It exhibits excellent rust‑proof and corrosion‑resistant properties.
Comparison:
304HC stainless steel balls are softer and easier to machine than 304 stainless steel balls, while 304L stainless steel balls offer superior rust and corrosion resistance compared to both, are easy to weld, exhibit excellent polishability, and are better suited for industries with stringent surface‑finish requirements.
