Special bearings, pumps and valves, aerosol and dispenser sprayers.
Utilised in the foodstuff, paper, chemical, rubber, military, textile industry.
Applications in photografic devices, medical instruments, quick couplings, recirculating balls, ink cartridges, jewels.
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.

|---|---|
Hardness*
|
Balls can be supplied in the ANNEALED (HRC 10-25) or COLD WORKED (HRC 25-39) conditions.
|
Magnetism
|
Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly depends by the manufacturing process, specific inquiries for not magnetic balls should priorly reported.
|
Precision grade**
|
On specifical request and for big quantities, we can supply G10 and G16 precision grade balls. Diameters from 3.000 mm to 1/2".
