What is the specific gravity of mild steel?

Question

What is the specific gravity of mild steel?

Answer 1

*Specific gravity of mild steel=7.861093

=7.86 UPTO 2 decimal.

[*Density of  mild steel is 7,861.093 kg/m³ (0.284 lb/in³)

(0.284 pound/cubic inch = 490.752 pound/cubic foot)

The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. Specific Gravity can be expressed as

SG = ρ / ρH2O

where

SG = specific gravity

ρ = density of fluid or substance (kg/m3)

ρH2O = density of water (kg/m3)

It is common to use the density of water at 4 Deg C (39oF) as reference - at this point the density of water is at the highest - 1000 kg/m3 or 62.4 lb/ft3.

*specific gravity of mild steel

=DENSITY of mild steel/density of water.

*SG mild steel

= ρ mild steel / ρH2O

=7,861.093 kg/m^3/1000 kg/m^3

=7.861093

=7.86 UPTO 2 decimal

OR

*SG mild steel

= ρ mild steel / ρH2O

=490.752 lb/ft^3 / 62.4 lb/ft^3

=7.8646153846153846153846153846154

==7.86 UPTO 2 decimal

Answer 2

just refer wikepedia

Answer 3

SG = 7.85

Density is 7850 kg/m3
