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
Special bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber,
