Question

What is stainless steel? How is it prepared? Write one important property which makes it more useful in making cooking utensils as compared to its primary metal. 

Hint:

Stainless steel’s ability to resist rust and maintain its strength under high heat is why it is the preferred material for cooking utensils.

Answer 1

F₂Stainless SteelF₂ is a corrosion-resistant alloy made primarily of:
- F₂Iron (Fe)F₂: 70-90%
- F₂Chromium (Cr)F₂: 10-20%
- F₂Nickel (Ni)F₂: 5-10%

Stainless steel is prepared by adding chromium and nickel to steel, which enhances its corrosion resistance, especially to rust and staining. It is widely used in cooking utensils and other kitchenware due to its non-reactive nature with food and its high durability.

F₂Important PropertyF₂:
The presence of chromium in stainless steel forms a thin, self-healing layer of chromium oxide on the surface, making it resistant to corrosion and stains. This property makes it much more suitable than pure iron for cooking utensils.
