| Corrosion Resistance |
| Extremely very good corrosion resistance with regard to organic and natural substances, oxidating options, foodstuff, sterilizing solutions. Very good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of scorching chloride answers and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 shows somewhat best corrosion resistance with respect to AISI 304/304L stainless steels. |
Notes
| Property | Description |
| Hardness* | Balls can be provided in the (one) Cold Worked (HRC 20-39, common merchandise) or (two) ANNEALED (HV one hundred-250, on demand from customers) situations. |
| Magnetism | Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly relies upon by the producing process, certain inquiries for not magnetic balls should priorly reported. |
| Precision Grade** | On specifical ask for and for huge quantities, we can provide G10 and G16 precision quality balls. Diameters from 3.000 mm to 1/two”. |
| Precision Grade** | On specifical request we can supply G20-24-twenty five-28-forty-forty eight-fifty-sixty-eighty precision quality balls. |
