What is carbon structural steel？
Carbon structural steel is carbon steel containing less than 0.8% carbon, this steel contains less sulfur, sulfur and phosphorus content less than 0.050% and 0.045% respectively，phosphorus and non-metallic inclusions than carbon structural steel, mechanical properties are better.
Carbon structural steel plate classification
1、Carbon structural steel can be divided into three types 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%).
2、Carbon structural steel can be divided into two groups with normal manganese content (0.25%-0.8% manganese content) and high manganese content (0.70%-1.20% manganese content) according to different manganese content. The latter has better mechanical and machining properties.
Carbon structural steel plate application
1. Ordinary carbon structural steel:Can be rolled into steel plate, steel bar, steel pipe，Section steel, steel plate, etc
2. High quality carbon structural steel:Mainly used for manufacturing various machine parts
