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 composed mainly of:
- F₂Iron (Fe)F₂: 70-90%
- F₂Chromium (Cr)F₂: 10-20%
- F₂Nickel (Ni)F₂: 5-10%

Stainless steel gains its corrosion resistance, especially against rust and staining, from the addition of chromium and nickel to steel. Its non-reactive properties with food and high durability make it ideal for cooking utensils and other kitchenware.

F₂Key FeatureF₂:
Chromium in stainless steel creates a thin, self-repairing chromium oxide layer on the surface. This layer provides resistance to corrosion and stains, making stainless steel superior to pure iron for cooking applications.
