Product Description
Carbon steel is divided into carbon structural steel, carbon tool steel, and free-cutting structural steel.
Carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel;
According to the smelting method, it can be divided into open hearth steel and converter steel;
According to the deoxidation method, it can be divided into boiling steel (f), killed steel (z), semi-killed steel (b) and special killed steel (TZ);
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%).
Item | Carbon structural steel bar |
Introduction | Carbon structural steel bar refers to carbon steel with less than 0.8% carbon. |
This kind of steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, |
and has better mechanical properties. Carbon structural steel can be divided into three categories |
according to different carbon content: low carbon steel (C≤0.25%), |
medium carbon steel (C is 0.25-0.6%) and high carbon steel (C>0.6%). |
According to different manganese content, carbon structural steel is divided into two groups: |
normal manganese content (manganese 0.25%-0.8%) and higher manganese content (manganese 0.70%-1.20%). |
The latter has better mechanical properties. And processing performance. |
