Corrosion Resistance 
Quite very good corrosion resistance with respect to natural substances, oxidating solutions, foodstuff, sterilizing solutions. Great resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of sizzling chloride solutions and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 exhibits slightly very best corrosion resistance with regard to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be provided in the (one) Cold Labored (HRC 20-39, regular product) or (two) ANNEALED (HV one hundred-250, on desire) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly relies upon by the producing procedure, distinct inquiries for not magnetic balls need to priorly described.
Precision Grade** On specifical ask for and for large quantities, we can offer G10 and G16 precision grade balls. Diameters from three.000 mm to 1/2″.
Precision Quality** On specifical request we can source G20-24-twenty five-28-40-forty eight-fifty-60-eighty precision grade balls.
