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
