aterial | Feature | General Applications |
AISI 420 | Magnetic, Harden-able, fair corrosion resistance | used for special bearings and valves where Balls requiring a combine -action of hardness and corrosion resistance |
AISI 440C | Magnetic, highest hardness, good corrosion resistance | used in bearing nozzles and valves where lubrication is poor or absent |
AISI 304 | austentitic, corrosion resistance, slightly magnetic, however annealing can makes it non - magnetic | Used in valves and relevant application , food products, aerosols, home sprays, perfumes and medical equipment. |
AISI 316 | non - magnetic, good corrosion resistance even when exposed to marine atmosphere and sulfuric acid. | used in presence of sulphuric, phosphoric and acetic acids. |
AISI 316 | Characteristics same as 316 but with excellent corrosion resistance, Lower carbon content than regular 316. | expecially used in Jewelry, and Human Implant Applications
