Question

Element present in the stainless steel is __________.
A. Iron
B. Chromium
C. Nickel
D. All of these

Answer 1

Hint: A mixture of metals combines and forms a new compound with special properties. This type of mixture of metals is called an alloy. Stainless steel is an example of alloy. Alloys have new advantageous properties when compared to pure metals.

Complete step by step answer:
- In the question it is given what are the elements present in stainless steel.
- We know that stainless steel is an alloy with a mixture of metals.
- The stainless steel contains iron, nickel and 10.5 % of chromium.
- Means stainless steel is an alloy containing a mixture of iron, nickel and chromium.
- Stainless steel is also called Inox steel (due to the presence of 10.5 % chromium) in metallurgy.
- Therefore stainless steel is an alloy.

So, the correct option is D.

Additional Information:
- Stainless steel is used in the preparation of kitchen sink and cookware.
- Stainless steel is used to prepare surgical tools and surgical implants etc.
- Monuments, bridges also contain stainless steel.
- Stainless steel is used in automotive and aerospace fields also.

Note: Stainless steel is an alloy and won’t corrode easily and does not lose its color. There are various grades in stainless steel. Generally stainless steel is used where we have to stop the formation of corrosion products. Stainless steel contains a minimum amount of carbon, manganese and silicon in its composition.
