Question

Increasing carbon content of steel ______ its ductility.

• A. increases
• B. decreases
• C. neither decrease nor increase
• D. carbon is not a component of steel

Answer 1

The correct option is B decreases

Materials are highly ductile because of their characteristic metallic bonds. As such, metals are generally ductile, but the composition of these metallic materials is not always pure. They have alloying constituents, which affects ductility. For example, increasing the carbon component of steel decreases its ductility.
