Production Description
| AISI 302/304/304L STAINLESS Metal BALLS |
| They screen great mechanical traits, toughness and corrosion resistance. AISI 304L gives lower carbon content material, AISI 302 far better mechanical qualities. Balls are provided in the passivated situation. |
| Applications |
| Stainless metal balls are broadly used in bearings, vehicles, bikes, bicycles, home appliances, chemical equipment, textile equipment, food machinery, mining equipment, devices, and other fields. |

| Corrosion Resistance |
| Really great corrosion resistance with respect to organic substances, oxidating remedies, foodstuff, sterilizing options. Great resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of scorching chloride options and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 demonstrates somewhat greatest corrosion resistance with respect to AISI 304/304L stainless steels. |
