Product Description
13.0mm AISI304 Sliver Stainless Steel Balls , Ss Ball Bearings For Crafts 8.961g
Production Description
Stainless steel balls do not rust, but are not easy to rust. The principle is that by adding chromium,
a layer of dense tissue of chromium oxide is formed on the surface of the steel, which can effectively
block the re-contact of the steel and the air, so that the oxygen in the air cannot enter the steel, thereby
preventing the steel from being produced. The effect of rust.
| AISI 302/304/304L STAINLESS STEEL BALLS |
| They display good mechanical characteristics, toughness and corrosion resistance. AISI 304L provides lower carbon content, AISI 302 better mechanical characteristics. Balls are provided in the passivated condition. |
| Applications |
| Special bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams, medical application valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and military industry. |

Corrosion Resistance |
| Very good corrosion resistance with respect to organic substances, oxidating solutions, foodstuff, sterilizing solutions. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 shows slightly best corrosion resistance with respect to AISI 304/304L stainless steels. |
Notes
| Property | Description |
| Hardness* | Balls can be supplied in the (1) COLD WORKED (HRC 20-39, standard product) or (2) ANNEALED (HV 100-250, on demand) conditions. |
| Magnetism | Eventual magnetism of AISI 316 balls and in general of all austenitc stainless steels strictly depends by the manufacturing process, specific inquiries for not magnetic balls should priorly reported. |
| Precision Grade** | On specifical request and for big quantities, we can supply G10 and G16 precision grade balls. Diameters from 3.000 mm to 1/2". |
| Precision Grade** | On specifical request we can supply G20-24-25-28-40-48-50-60-80 precision grade balls. |
