Corrosion Resistance 
Extremely great corrosion resistance with respect to natural and organic substances, oxidating answers, foodstuff, sterilizing options. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of sizzling chloride remedies and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 displays slightly greatest corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (1) Chilly Worked (HRC 20-39, regular solution) or (two) ANNEALED (HV 100-250, on demand) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly depends by the production method, specific inquiries for not magnetic balls must priorly noted.
Precision Grade** On specifical ask for and for huge portions, we can source G10 and G16 precision quality balls. Diameters from 3.000 mm to one/2″.
Precision Grade** On specifical request we can offer G20-24-twenty five-28-40-forty eight-fifty-60-eighty precision grade balls.
