Example questions

Example 1 · 1 mark · multiple choice

Which group contains only non-ferrous metals?

  1. AMild steel, cast iron and stainless steel
  2. BAluminium, mild steel and copper
  3. CBrass, cast iron and zinc
  4. DAluminium, copper and brass

Example 2 · 1 mark · multiple choice

Mild (low-carbon) steel typically contains about

  1. A0.6–1.4% carbon
  2. B0.1–0.3% carbon
  3. C1.5–2.5% carbon
  4. D2–4% carbon

Example 3 · 5 marks · short answer

A centre punch has been made from high-carbon steel. Describe the heat treatment processes used to make it hard enough to mark steel but tough enough not to shatter when struck.
