Heat treatment: effects of normalising on steel properties For plain carbon steels after normalising, identify the combined property changes relative to the annealed condition. Choose the correct set of effects.

Difficulty: Easy

Yield point increases
Ductility decreases
Ultimate tensile strength increases
All of these

Correct Answer: All of these

Explanation:

Given

Normalising heat treatment of steel.

Concept
Normalising refines grain size and produces a more uniform pearlitic/ferritic structure than annealing. This typically raises strength (UTS), raises yield point, and reduces ductility compared with the annealed state.

Final Answer
All of these
