Final answer:
Steel is an iron-carbon alloy typically containing 0.02% to about 2.1% carbon. The range of 0.02% to 4% or 5% stated for carbon content in steel is false, as the carbon content does not exceed 2.5%. Therefore, the correct answer is B. False.
Step-by-step explanation:
Steel, which is an iron-carbon alloy, typically contains carbon in varying percentages to impart different properties to the alloy. The amount of carbon present in steel significantly affects its strength, hardness, and workability. Common carbon content in steel ranges from 0.02% to about 2.1%, which allows for various classifications of steel, such as mild steel and high carbon steel.
Mild steel is a type of steel containing up to about 0.25% carbon, commonly used for a wide range of applications including nails, wire, and construction materials. High carbon steel, on the other hand, can contain up to about 1.5% carbon and is known for its hardness and brittleness, which makes it suitable for cutting tools and other applications where a harder steel is required.
To address the question: Does steel which is an iron-carbon alloy contains from carbon 0.02% to about 4% or 5%? The answer is B. False. The typical carbon content in steel does not exceed 2.5%, making the range of 0.02% to 4% or 5% incorrect.
