Manufacturing Description
| AISI 302/304/304L STAINLESS Steel BALLS |
| They exhibit great mechanical characteristics, toughness and corrosion resistance. AISI 304L gives lower carbon material, AISI 302 much better mechanical characteristics. Balls are presented in the passivated condition. |
| Purposes |
| Stainless metal balls are extensively utilized in bearings, cars, motorcycles, bicycles, house appliances, chemical equipment, textile machinery, food machinery, mining machinery, devices, and other fields. |

| Corrosion Resistance |
| Really very good corrosion resistance with regard to natural and organic substances, oxidating answers, foodstuff, sterilizing answers. Very good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of sizzling chloride options and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 shows slightly greatest corrosion resistance with regard to AISI 304/304L stainless steels. |
Notes
