Manufacturing Description
| AISI 302/304/304L STAINLESS Metal BALLS |
| They display good mechanical qualities, toughness and corrosion resistance. AISI 304L provides lower carbon content, AISI 302 better mechanical traits. Balls are supplied in the passivated problem. |
| Programs |
| Specific bearings and pumps, aerosol pumps, gardening and family sprayers, perfume miniature pumps, seams, health care application valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and armed forces sector. |

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