Solution

The strength of steel is not solely determined by the process of annealing or normalising. Both processes can improve the strength of steel, but the final outcome also depends on the specific chemical composition of the steel.

  1. Annealing: This process involves heating the steel to a high temperature and then slowly cooling it. This can help to refine the grain structure and increase the ductility and toughness of the steel, which can indirectly increase its strength.

  2. Normalising: This process involves heating the steel to a high temperature and then cooling it in still air. This also refines the grain structure and improves the machinability, strength, and ductility of the steel.

  3. Chemical Composition: The specific elements present in the steel, such as carbon, manganese, and others, also play a significant role in determining its strength. Different compositions can result in different strengths, even after annealing or normalising.

So, the answer is "Both above, it depends on the chemical composition of the steel".
