Air Bearings
WHY 440C STAINLESS steel?
Good corrosion resistance to water and many weak chemicals.
Corrosion resistance can be improved by passivation.
Good for temperatures up to 300°C.
Slightly softer than chrome steel so lower load ratings.
Will corrode in salt water or salt spray and poor resistance to acids/alkalis.
More expensive than chrome steel.
