316 Stainless Steel Balls
Austenitic stainless steel balls with higher corrosion resistance than AISI 304 balls. They show good toughness.
AISI 316 has a lower carbon content (maximum 0,030%).
Balls are provided in the passivated condition.
Applications: |
|---|
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. |

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.
