High quality carbon structural steel plate

High-quality carbon structural steel is carbon steel with carbon content less than 0.8%, which contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and has better mechanical properties.

High-quality carbon structural steel can be divided into three categories according to the carbon content: low carbon steel (C≤0.25%), medium carbon steel (C 0.25-0.6%) and high carbon steel (C > 0.6%).

According to the different manganese content, high-quality carbon structural steel is divided into normal manganese content (manganese content 0.25%-0.8%) and high manganese content (manganese content 0.70%-1.20%), the latter has better mechanical properties and processing properties.
