Heat treatment effects on mild steel’s mechanical properties
Abstract
This report is determining the heat treatment effect on material mechanical
properties. Mild steel is the most common form of steel as its price is relatively low
while it provides material properties that are acceptable for many applications. It can
be heat treated to produce the desired microstructure and properties. The desired
results are accomplished by heating and cooling at the specified temperature. The
annealing and normalizing heat treatments method on mild steel have been
investigated in this paper. The purpose of this study is investigating the mechanical
properties of mild steel after full annealing and normalizing. After heat treatment
process, the mild steel’s microstructure has been changed to pearlite and ferrite. The
elongation of mild steel after full annealing process is higher than normalizing process.
However, the ultimate strength and hardness of mild steel after normalizing is greater
than full annealing.
