Feature
Austenitic stainless steel balls with higher corrosion resistance
than AISI 304 balls. They show good toughness.
AISI 316L has a lower carbon content (maximum 0,030%). Balls are
provided in the passivated condition.
Corrosion Resistance
Very good corrosion resistance with respect to organic substances, good resistance to several strong acids
(acetic, phosphoric, sulphuric acid) and on sea water.
They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and
to stress corrosion when temperature exceeds 60°C.
They do not resist in contact with hydrochloric and hydrofluoric
acids, aqua regia, iron and magnesium chlorides.
They are subjected to pitting corrosion in sea water environments.
Poor corrosion resistance in acid environments.
Application Of Steel Balls
Special bearings, pumps and valves, aerosol and dispenser sprayers.
Utilised in the foodstuff, paper, chemical, rubber,
military, textile industry. Applications in photographic devices, medical instruments, quick couplings, recirculating balls,
ink cartridges, jewels.
