Key Features:

• Carbon Class: The carbon steel broadly classified into low, medium, and high carbon steel based on the carbon content present.
• Mechanical Properties: More carbon generally increases hardness and strength but reduces ductility.
• Versatile Applications: The applications are in construction, automotive, tools, and pipelines.

The main point of carbon steel is that it maintains a balance of strength, durability, and costs, making it one of the most widely-used materials. It's used in various industries, including construction, transport, and manufacture. Alloy advancements and modern heat treatments have improved the properties of carbon steel for specialized applications.
