Q:

What is the unit weight of steel?

A:

Quick Answer

Steel weighs 7850 kilograms per cubic meter, or 489.8 pounds per cubic foot. Stainless steel weighs between 7480 and 8000 kilograms per cubic meter, depending on its exact composition. A 0.25-inch-thick steel plate weighs 10.2 pounds per square foot.

Full Answer

Steel is an alloy of iron and carbon. Steel is created by heating iron in the presence of oxygen. Iron is a soft, malleable metal. Adding 1.5 to 2 percent carbon creates steel, which is a stronger but less malleable metal. Stainless steel is steel with varying amounts of chromium added to prevent rust from forming. Cast iron is steel with a carbon content higher than 2 percent. It is not malleable but can be melted and cast in molds.

  • Q:

    Why does steel rust?

    A:

    Steel rusts because of chemical reactions that occur when it comes into contact with water and oxygen. Iron, one component of steel, combines with water and oxygen to produce hydrated iron (III) oxide, which is the chemical that we call rust.
