304 316 non-magnetic stainless steel bearings Compared with ordinary stainless steel bearings, the advantages

(1) The corrosion resistance is good. Ordinary stainless steel cannot be corrosion resistant and will be corroded in an acid-base environment, while 304 316 stainless steel can be used in a strong environment.

(2) Anti-rust, it will never rust even if placed in water

(3) Non-magnetic. Generally, 440 stainless steel bearings are very magnetic. Magnets can be used to attract them, but 304 316 will not, especially 316 materials can be completely non-magnetic.
