Question 101
2 marks · Easy
Answer and see the solution →A manufacturer needs a material that is both malleable and can be drawn into wires for making bridges and electrical cables. Suggest which type of steel from the following is best suited, and give one reason using its properties.
Type of steel Properties Mild steel Strong, malleable, ductile, High-carbon steel Hard, wear-resistant, brittle Stainless steel Corrosion-resistant, less malleable (a)[2 marks]Give the name of the type of steel and one property that makes it suitable.

Question 103
4 marks · Normal
Answer and see the solution →The properties of different steels determine their uses.
(a)[2 marks]Explain why mild steel is used for car bodies.
(b)[2 marks]Explain why high-carbon steel is preferred for cutting tools rather than mild steel.
Question 104

Answer and see the solution →Explain why stainless steel is more suitable than mild steel for kitchen sinks. Your answer should mention at least two properties of each material.
Question 105
2 marks · Normal
Answer and see the solution →State one advantage and one disadvantage of using high-carbon steel instead of mild steel for making nails.
Question 106
4 marks · Normal
Answer and see the solution →Two companies plan to produce saucepans and garden spades. They are choosing between mild steel, high-carbon steel, and stainless steel.
(a)[1 mark]Explain, with one property, why stainless steel is preferred over mild steel for saucepans.
(b)[1 mark]State a key property of high-carbon steel that makes it better than mild steel for the blade of a garden spade.
