Material
Feature
General Applications
AISI420
Magnetic, Harden-able, fair corrosion resistance
used for special bearings and valves where Balls requiring a combine -action of hardness and corrosion resistance
AISI440
Magnetic, highest hardness, good corrosion resistance
used in bearing nozzles and valves where lubrication is poor or absent
AISI304
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.
AISI316
non-magnetic, good corrosion resistance even when exposed to marine atmosphere and sulfuric acid.
used in phosphoric and acetic acids. Mainly used in chemical, paper and textile industries.
AISI316L
Characteristics same as 316 but with excellent corrosion resistance, Lower carbon content than regular 316.
especially used in Jewelry, and Human Implant Applications
