Question

Steel is preferred over iron in construction of ships because:

• A. melting point of steel is higher than iron
• B. steel is more uniform than iron
• C. steel does not rust
• D. tensile strength of steel is not high

Answer 1

The correct option is C steel does not rust

The material chosen for the construction of a ship is a balance between strength, corrosion resistance, workability and cost. High tensile steels are used in ships.

Steel remains stainless or does not rust because of the interaction between its alloying elements and the environment. Stainless steel contains iron, chromium, molybdenum, manganese, silicon, carbon, nickel etc

Hence, the correct option is $\text{C}$
