Solution
In stainless steel alloy, iron metal is mixed with Cr and Ni.
Explanation:
Stainless steel is an alloy created by mixing iron with chromium (Cr) and nickel (Ni) to drastically alter its properties. Chromium forms a microscopic protective oxide layer on the surface, making the alloy highly resistant to corrosion and rust. Nickel is added to enhance this corrosion resistance while simultaneously increasing the alloy's overall strength, durability, and formability.
