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


Property  Description
Hardness* Balls can be equipped in the (one) Chilly Worked (HRC 20-39, standard solution) or (2) ANNEALED (HV one hundred-250, on need) problems.
Magnetism Eventual magnetism of AISI 316 balls and in standard of all austenitc stainless steels strictly is dependent by the producing approach, distinct inquiries for not magnetic balls must priorly documented.
Precision Grade** On specifical ask for and for large portions, we can supply G10 and G16 precision quality balls. Diameters from 3.000 mm to 1/two”.
Precision Grade** On specifical request we can supply G20-24-25-28-40-forty eight-50-sixty-80 precision grade balls.
