STAINLESS STEEL BALLS
AISI 302 - AISI 304 - AISI 304-L (V2A)

Unhardened low-magnetic austenitic materials with an axcellent resistance to corrosion against organic chemicals, oxidising solutions, food products and sterilising solutions, while they are less resistant to sulphuric acids in general.

All balls can be annealed and passivated.

The most common applications include: aerosol pumps, gardening and home sprays guns, micro-pumps for parfume sprays, valves for medical equipment, agricultural spraying pumps. AISI 304L offers lower carbon content.

Diameters: from mm 0,50 to mm 150

Equivalent materials to international standards:
