Creation Description
| AISI 302/304/304L STAINLESS Metal BALLS |
| They screen great mechanical attributes, toughness and corrosion resistance. AISI 304L supplies lower carbon content, AISI 302 better mechanical qualities. Balls are offered in the passivated condition. |
| Programs |
| Unique bearings and pumps, aerosol pumps, gardening and family sprayers, fragrance miniature pumps, seams, medical application valves, agricultural backpack sprayers. They are employed in foodstuff, aerospace and armed forces industry. |

| Corrosion Resistance |
| Very very good corrosion resistance with regard to natural and organic substances, oxidating answers, foodstuff, sterilizing remedies. Great resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of hot chloride remedies and to anxiety corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 displays marginally best corrosion resistance with regard to AISI 304/304L stainless steels. |
Notes
| Property | Description |
| Hardness* | Balls can be supplied in the (1) Cold Worked (HRC 20-39, regular solution) or (2) ANNEALED (HV 100-250, on need) problems. |
| Magnetism | Eventual magnetism of AISI 316 balls and in common of all austenitc stainless steels strictly is dependent by the production approach, particular inquiries for not magnetic balls should priorly documented. |
