Manufacturing Description
| AISI 302/304/304L STAINLESS Steel BALLS |
| They exhibit good mechanical traits, toughness and corrosion resistance. AISI 304L gives lower carbon material, AISI 302 far better mechanical characteristics. Balls are supplied in the passivated issue. |
| Programs |
| Specific bearings and pumps, aerosol pumps, gardening and household sprayers, fragrance miniature pumps, seams, health-related application valves, agricultural backpack sprayers. They are utilised in foodstuff, aerospace and armed forces business. |

| Corrosion Resistance |
| Very excellent corrosion resistance with regard to organic and natural substances, oxidating options, foodstuff, sterilizing solutions. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of very hot chloride remedies and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 shows slightly very best corrosion resistance with regard to AISI 304/304L stainless steels. |
Notes
