Production Description
| AISI 302/304/304L STAINLESS Steel BALLS |
| They screen good mechanical traits, toughness and corrosion resistance. AISI 304L offers lower carbon content material, AISI 302 much better mechanical attributes. Balls are presented in the passivated problem. |
| Applications |
| Stainless steel balls are widely utilized in bearings, vehicles, bikes, bicycles, family appliances, chemical machinery, textile equipment, foods equipment, mining equipment, devices, and other fields. |

| Corrosion Resistance |
| Quite good corrosion resistance with respect to organic and natural substances, oxidating answers, foodstuff, sterilizing remedies. Very good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of scorching chloride remedies and to pressure corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid answers. AISI 302 shows marginally best corrosion resistance with regard to AISI 304/304L stainless steels. |
Notes
