What are the characteristics of carbon steel

According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25% - 0.6%) and high carbon steel (WC > 0.6%);

The characteristics are generally comparative strength, hardness, plasticity, weldability, etc. for example, low carbon steel has low strength, low hardness, good plasticity and weldability.
