304 stainless steel balls
Application fields:
The 304 stainless steel ball is a widely used type of steel ball on the market. It can be applied in medical devices, chemical industry, aerospace, plastic and hardware: perfume bottles, sprayers, valves, nail polish, motors, switches, electric irons, washing machines, refrigerators, air conditioners, automotive parts, bearings, instruments, baby bottles. Features:
The typical representative of austenitic steel is usually non-magnetic, but it becomes magnetic after being polished and can be demagnetized. Its hardness is HRC ≤ 26. It has excellent rust and corrosion resistance properties.
Comparison:
The 304HC stainless steel ball is softer and easier to process than the 304 stainless steel ball. Meanwhile, the 304L stainless steel ball has stronger rust and corrosion resistance compared to both of the above, is easy to weld, has excellent polishing properties, and is suitable for applications with high surface requirements.
