STAINLESS STEEL BALLS AISI 302 - AISI 304 - AISI 304-L
Unhardened anti-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 are 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 0,40 to mm 150
Equivalent materials to international standards: AISI 302, 304, 304L-W1.4300-W1.4301-AFN Z6CN18.09 - B.S. EN58E -JIS SUS304 - DIN X5CrNi 18.09 - UNI X5CrNi 1810
