Question

Mild steel is considered to have________

a. No carbon content
b. Low carbon content
c. Medium carbon content.
d. High carbon content.

Answer 1

Mild steel is considered to have a low carbon content, specifically up to about 0.25%, which provides a balance between strength and ductility suitable for various construction applications.

Step-by-step explanation:

Mild steel is considered to have b. Low carbon content. It contains up to about 0.25% of carbon, which makes it stronger and harder than pure iron without the brittleness that higher carbon content would cause. Unlike wrought iron, which is quite soft with high purity, mild steel offers structural strength and is commonly used in a variety of applications, such as the construction of nails, wire, car bodies, ship building, girders, and bridges. In contrast, high carbon steel, which contains up to about 1.5% carbon, is very hard and more brittle, suitable for cutting tools.
