Question

Compare Mild Steel & High tensile steel used in the construction industry

Answer 1

MILD STEEL

1) Mild steel is basically a low carbon steel having a carbon content of 0.1 - 0.25 percent . Due to its low carbon content it is also called as Low Carbon Steel

2) Mild Steel has got very High Ductility property in them , The reason is low carbon content . Low carbon content results in decrease in strength and brittleness but increased Ductility .\

3) Mild steel is used in rolled sections , reinforcing bars etc

4) Ultimate strength of Mild steel Varies from 600 to 800 Mpa .

5) Rusting is Mild steel is very rapid when compared to High strength Steel

High Tensile Steel

1) High tensile Steel is having Carbon content 0.6 -0.8 percent . Due to its more Carbon content it is also referred as Medium Carbon Steel

2) High Strength Steel has low value of ductilty when compared to MS and more Strength . The reason is more Crbon Content

3) Due to its High Strength , they are preferred in prestress concrete since the have to bear high value of losses in the structure .

4) Ultimate Strength of High tensile Steel ranges around 2000 Mpa.

5) High Strength Steel does not catches rusting easily when Compared with MS
