Creation Description
| AISI 302/304/304L STAINLESS Steel BALLS |
| They display very good mechanical characteristics, toughness and corrosion resistance. AISI 304L supplies lower carbon articles, AISI 302 far better mechanical characteristics. Balls are presented in the passivated situation. |
| Purposes |
| Special bearings and pumps, aerosol pumps, gardening and household sprayers, fragrance miniature pumps, seams, medical application valves, agricultural backpack sprayers. They are utilised in foodstuff, aerospace and armed forces business. |

| Corrosion Resistance |
| Really excellent corrosion resistance with regard to natural 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 scorching chloride options and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 demonstrates slightly best corrosion resistance with regard to AISI 304/304L stainless steels. |
Notes
