Solution(By Examveda Team)

Chromium is a powerful alloying element in steel. Cr presents in certain structural steels in small amounts.
It is primarily used to increase hardenability of steel and increase the corrosion resistance as well as the yield strength of the steel material.
For that reason often occurs in combination with nickel and copper. Stainless steels may contain in excess of 12% chromium.
