Manufacturing Description
| AISI 302/304/304L STAINLESS Metal BALLS |
| They show excellent 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 issue. |
| Programs |
| Particular bearings and pumps, aerosol pumps, gardening and home sprayers, fragrance miniature pumps, seams, medical software valves, agricultural backpack sprayers. They are utilized in foodstuff, aerospace and army market. |

| Corrosion Resistance |
| Extremely good corrosion resistance with regard to organic and natural substances, oxidating answers, foodstuff, sterilizing solutions. Very good resistance with respect 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 answers. AISI 302 shows slightly greatest corrosion resistance with regard to AISI 304/304L stainless steels. |
