Creation Description
| AISI 302/304/304L STAINLESS Steel BALLS |
| They display excellent mechanical traits, toughness and corrosion resistance. AISI 304L gives lower carbon content, AISI 302 better mechanical attributes. Balls are presented in the passivated problem. |
| Applications |
| Special bearings and pumps, aerosol pumps, gardening and house sprayers, perfume miniature pumps, seams, healthcare application valves, agricultural backpack sprayers. They are employed in foodstuff, aerospace and military business. |

| Corrosion Resistance |
| Really very good corrosion resistance with regard to natural and organic substances, oxidating answers, foodstuff, sterilizing remedies. Good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of scorching chloride options and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 exhibits a bit ideal corrosion resistance with respect to AISI 304/304L stainless steels. |
Notes
