Carbon structural steel

High quality carbon structural steel is carbon is less than 0.8% of the carbon steel, the steel contains sulfur, phosphorus and non-metallic inclusion less than carbon structural steel, mechanical performance is relatively good.

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

High quality carbon structural steel according to the divided into normal manganese content in manganese content (including manganese 0.25% - 0.8%) and high manganese content (0.70% 1.20%) manganese content in the two groups, the latter has better mechanical properties and processability.

1, high quality carbon structural steel, hot rolled steel sheet and strip

High quality carbon structural steel plate knowledge hot rolled steel sheet and strip used in automobile, aviation industry and other departments. The steel grades for rimming steel 08 f, 10, 15 f f; Killed steel: 08, 08 al, 10, 15, 20, 25, 30, 35, 40, 45, 50. 25 and under 25 for low carbon steel plate, more than 30 and 30 for medium carbon steel plate.

2, high quality carbon structural steel, hot rolled steel plate and steel band wide thick

High quality carbon structural steel plate and width of hot rolled steel strip used for various mechanical structure. Its steel grades for low carbon steel include: 05, 08 f, 08 f, 10 f, 10, 15, 15, 20 f f, 20, 25, 20 mn, 25 mn, etc.; Medium carbon steel include: 30, 35 and 40, 45, 50, 55, 60, 30 mn, 40 mn, 50 mn, 60 mn, etc.; High carbon steel include: 65, 70, 65 mn, etc.
