S.S.304 / S.S.304L BALLS (Non-magnetic and Unhardened) :

Balls manufactured from S.S.304 and S.S.304L materials are non-magnetic and unhardened and are precisely ground and lapped to mirror finish. These Balls have good resistance to atmospheric corrosion, dyes, foodstuffs, sterilizing solutions, oxidizing agents and organic substances. S.S.304 and S.S.304L Balls are mainly used in Special Bearings, Pumps, Valves, Instruments, Sprayers, Perfumes, Electronics, Medical, Agro and Food Processing Industries.
S.S.304L Balls have higher corrosion resistance than S.S.304 Balls because of lower carbon content.
