Question

Stainless steel contains in addition to Iron, Nickel and Chromium which imparts

• A. Hardness to the alloy
• B. Tensile strength to the alloy
• C. Luster to the alloy
• D. None of these

Answer 1

The correct option is B

Tensile strength to the alloy

The explanation for correct option:

Option (B) Tensile strength to the alloy

• Modern stainless steel may contain Nickel ($\mathrm{Ni}$), Niobium ($\mathrm{Nb}$), Molybdenum ($\mathrm{Mb}$), and Titanium ($\mathrm{Ti}$) in addition to Iron ($\mathrm{Fe}$), Carbon ($\mathrm{C}$), and Chromium ($\mathrm{Cr}$).
• Nickel, Niobium, Molybdenum, and Chromium increase stainless steel corrosion resistance.
• As a result, stainless steel, in addition to Iron, Nickel, and Chromium, gives the alloy tensile strength.

Hence, Stainless steel contains in addition to Iron, Nickel, and Chromium which imparts option (B) tensile strength to the alloy.
