Question

Steel physical and chemical properties and its uses.Mention it.

Answer 1

The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.

Answer 2

⭐ Physical properties of steel

Steel has a density of 7,850 kg/m3, making it 7.85 times as dense as water. Its melting point of 1,510 C is higher than that of most metals. In comparison, the melting point of bronze is 1,040 C, that of copper is 1,083 C, that of cast iron is 1,300 C, and that of nickel is 1,453 C. Tungsten, however, melts at a searing 3,410 C, which is not surprising since this element is used in light bulb filaments.

Steel's coefficient of linear expansion at 20 C, in µm per meter per degree Celsius, is 11.1, which makes is more resistant to changing size with changes in temperature than, for example, copper (16.7), tin (21.4) and lead (29.1).
