Chromium!
Chromiun is the primary metallic element added to steel to make stainless steel.
No, stainless steel is not a nonmetallic element. It is a metallic alloy composed mainly of iron, with a minimum of 10.5% chromium to give it its corrosion-resistant properties.
Molybdenum
It is the 24th element. The confusion arises because it is the key alloying element added to steel to make it stainless.

Steel with chroniuum added
Yes, cobalt is sometimes added to stainless steel as a minor alloying element to improve strength and corrosion resistance. However, its presence is typically very small, with most stainless steels containing less than 1% cobalt.
stainless steel
While stainless steel is an alloy of steel, the primary difference between stainless steel and other steels is that the stainless steels have a high percentage (about 10% or even more) of the element chromium in them.
why are other metals added to stainless steel
If you are referring to stainless steel then one of the features that characterize stainless steels is a minimum 10.5% chromium content as the principal alloying element. The 'recipes' for making stainless steel are many and varied.
