Question

How do the properties of iron change when :

i) small quantity of carbon is mixed with it.

ii) nickel and chromium are mixed with it.

Explain in detail.

Answer 1

1. Iron becomes hard when 0.05% of carbon is added to it
2. Iron becomes Stainless Steel.it does not corrode easily

Answer 2

Hello....

i) Small quantity of carbon is mixed with it.

= Small quantity of carbon becomes strong and hard.

When we add small quantity of carbon and we know that alloy has very high strength and alloy has ability to alerted by heat treatment And formed alloy is known as steel.

ii) Nickel and chromium mixed with it.

= When Nickel and​ chromium are mixed with it becomes strong and corrosion resistant.

When we add nickel and chromium in steel then high resistance is enhanced with heat resistance and it's tensile strength increases Alloy formed is known as stainless steel.
