These alloys have better mechanical strength, elastic
modulus, abrasion resistance and corrosion resistance
compared to that of stainless steel. As with stainless steel,
chromium in these alloys provides the essential corrosion
resistance. But in contrast to that of the stainless steel, cobalt
also contributes to the corrosion resistance and this makes
cobalt-chromium based alloys to have excellent corrosion
resistance
