Manufacturing Description
| AISI 302/304/304L STAINLESS Metal BALLS |
| They show excellent mechanical qualities, toughness and corrosion resistance. AISI 304L gives lower carbon content, AISI 302 far better mechanical qualities. Balls are supplied in the passivated issue. |
| Programs |
| Specific bearings and pumps, aerosol pumps, gardening and house sprayers, perfume miniature pumps, seams, healthcare software valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and navy sector. |

| Corrosion Resistance |
| Very excellent corrosion resistance with respect to organic and natural substances, oxidating solutions, foodstuff, sterilizing solutions. Excellent resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of hot chloride remedies and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid options. AISI 302 shows somewhat very best corrosion resistance with regard to AISI 304/304L stainless steels. |
Notes
| Property | Description |
| Hardness* | Balls can be equipped in the (1) Chilly Labored (HRC 20-39, normal solution) or (two) ANNEALED (HV one hundred-250, on demand from customers) circumstances. |
| Magnetism | Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly depends by the manufacturing method, particular inquiries for not magnetic balls ought to priorly reported. |
| Precision Quality** | On specifical request and for massive quantities, we can source G10 and G16 precision grade balls. Diameters from 3.000 mm to 1/two”. |
| Precision Grade** | On specifical request we can offer G20-24-twenty five-28-40-48-50-60-80 precision quality balls. |
