thermal expansion depends on Temperature and material of steel
steel
No, steel is neither a thermal (heat) nor electrical insulator
80.45
All matter has thermal properties, so yes.
Yes. As with most metals, steel is a good conductor of heat.
It depends on what you compare it to. Steel has a thermal conductivity about 100 times greater than insulation, but is less conductive than materials such as ceramic or copper.
Because of the thermal compactablity of the steel the material is used in concrete
heated up to kindling temperature of the mild steel
no The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance. Note that the electrical and thermal conductivity are slightly altered. As with most strengthening techniques for steel, Young's modulus is unaffected.
A thermal conductor allows heat to readily flow through itself. An example of a material with a low thermal conductivity would be air, and an example of a material with a high thermal conductivity would be steel.
Low resistance to fire, and high thermal expansion.
