Q: The one that has least carbon content is:
  • A. Wrought iron
  • B. Cast iron
  • C. Mild steel
  • D. Pig steel
Correct Answer: Option A - Pig iron is a basic raw material for all irons & produced from a blast furnace. Pig iron contains C% equal to 3–4% • Pig iron are the basic form of iron. (a) Cast iron- 2–5% Carbon, made from cupola furnace. (b) Wrought iron- 0.05 - 0.15% carbon, made from pudding furnace. (c) Steel- Upto 1.5% carbon, Made from Bessemer converter steel is of there types- (i) carbon steal (Low, medium, high) (ii) Stainless steal (iii) Alloy steal
