Corrosion Resistance 
Quite great corrosion resistance with regard to natural and organic substances, oxidating solutions, foodstuff, sterilizing answers. Good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of very hot chloride remedies and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 shows slightly ideal corrosion resistance with regard to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (one) Chilly Worked (HRC 20-39, standard product) or (2) ANNEALED (HV 100-250, on demand from customers) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly relies upon by the producing method, specific inquiries for not magnetic balls should priorly described.
Precision Grade** On specifical ask for and for massive portions, we can supply G10 and G16 precision grade balls. Diameters from three.000 mm to one/2″.
Precision Grade** On specifical ask for we can supply G20-24-25-28-forty-48-50-60-80 precision quality balls.
