What is a carbon steel plate?

According to the strength of the products are divided into low carbon structural steel plate and high carbon structural steel plate. Steel plate is featured with hot working and cutting performance, poor welding performance. Strength and hardness is higher than low carbon steel while the plasticity and toughness are lower. As a carbon structural steel plate supplier we can supply steel plate in hot rolled or cold drawn state, it get better performance after heat treatment process.

Low carbon steel plates are often used as a general-purpose tooling metal because of its mechanical structure and ease of machinability. Hot rolled carbon steel plate and sheet are ideal for drilling, grinding, and tapping. Carbon steel also provides exceptional welding properties for a range of applications.

Carbon steel is broken down into four classes based on carbon content:

  • Low-carbon steel. 0.05 to 0.15% carbon (plain carbon steel) content.
  • Medium-carbon steel. Approximately 0.3–0.5% carbon content. …
  • High-carbon steel. Approximately 0.6 to 1.0% carbon content. …
  • Ultra-high-carbon steel. Approximately 1.25–2.0% carbon content.
