Question: What is the primary purpose of annealing a carbon steel component?
Answer options:
- To increase its hardness and wear resistance. ✅ To relieve internal stresses, soften the material, and improve ductility.
- To improve its ability to resist corrosion at high temperatures.
- To achieve a finer grain structure for increased yield strength.
Correct answer: To relieve internal stresses, soften the material, and improve ductility.
Explanation: Annealing is a heat treatment process primarily used to relieve internal stresses, reduce hardness, increase ductility, and improve the machinability of carbon steel. It involves heating the steel above its critical temperature, holding it, and then slowly cooling it. Other options describe different heat treatment objectives.
