Among layman, the reason for steel’s dominance is usually con- sidered to be the abundance of iron ore (iron is the principal ingredient in all steels) and/or the ease by which it can be refined from ore.See all results for this questionsp.info How does heat treatment affect the hardness of steel?This heat treatment process carried out for steel parts which have been already hardened, in order to reduce bitterness and unequal stress develop as a result of hardening. This process reduces brittleness and hardness but improves the tensile strength of Steel. It increases the toughness of Steel at the expenses of loss of some hardness.See all results for this questionsp.info Which is an example of a heat treatment process?By Heat Treatment process, Example: The plain carbon steel. The following changes may be achieved: The hardness of Steel may be increased or decreased. Internal stresses that are set up due to cold or hot working may be relieved. The machinability of Steel may be enhanced.See all results for this question
