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.Mainly used in chemical, paper and textile industries.

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
