yield strengths of 187 to 758 megapascals. Structural steel
made of alloys has values from 366 to 1793 megapascals.
6. Melting point
There is no defined value for melting point due to the wide
variations in types of structural steel. Melting point is the
temperature at which object starts to melt when heated.
7. Specific heat
Specific heat or heat capacity is the amount of heat which
needs to be applied to the object to raise its temperature by a
given amount. A higher value of specific heat denotes greater
insulation ability of the object. Values are measured in Joules
per Kilogram Kelvin. Structural steel made of carbon has
values from 450 to 2081 and that made from alloys has values
ranging from 452 to 1499.
Hardness is the resistance of an object to shape change when
force is applied. There are 3 types of hardness measurements.
Scratch, indentation and rebound. Structural steel made by
using alloys has hardness value between 149-627 Kg.
Structural steels made of carbon has value of 86 to 388 Kg.
