Chromium
in stainless steel provides:
Corrosion resistance
Less
ductility
Low toughness
Hardenability
Corrosion resistance
●Chromium
is added to steel to increase resistance to oxidation.
●Stainless
steels have a minimum of 10.5% chromium.
●
The corrosion resistance is due to the formation of a self-repairing passive
layer of chromium oxide on the surface of the stainless steel.
Hence,
the correct option is (A).
