High-quality carbon structural steel plate

 High-quality carbon structural steel plate

　　High-quality carbon structural steel is carbon steel with a carbon content of less than 0.8%. This steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and has better mechanical properties. According to the carbon content, it can be divided into three categories: low carbon steel (C≤0.25%), medium carbon steel (C is 0.25%~0.6%) and high carbon steel (C>0.6%); The manganese content is divided into two groups: normal manganese content (0.25%-0.8% manganese content) and higher manganese content (0.70%-1.20% manganese content), the latter has better mechanical and processing properties.

　　1. High-quality carbon structural steel hot-rolled thin steel plate and steel strip

　　High-quality carbon structural steel hot-rolled sheets and strips are used in the automotive, aerospace industries and other sectors. The grades of the steel are boiling steel: 08F, 10F, 15F; killed steel: 08, 08AL, 10, 15, 20, 25, 30, 35, 40, 45, 50. 25 and below are low carbon steel plates, 30 and below Above 30 is a medium carbon steel plate.

　　2. High-quality carbon structural steel hot-rolled thick steel plate and wide steel strip

　　High-quality carbon structural steel hot-rolled thick steel plates and wide steel strips are used for various mechanical structural parts. The steel grades are low carbon steel including: 05F, 08F, 08, 10F, 10, 15F, 15, 20F, 20, 25, 20Mn, 25Mn, etc.; medium carbon steel includes: 30, 35, 40, 45, 50, 55, 60, 30Mn, 40Mn, 50Mn, 60Mn, etc.; high carbon steel includes: 65, 70, 65Mn, etc.

Introduction to 20 # carbon steel plate

图片
Introduction to 20 # carbon steel plate       20 # belongs to superior carbon steel, which complies with GB/T711 standard. 20% of 20 # steel refers to carbon content, which is 0.2%, belonging to low carbon steel. Steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Mild steel - carbon content is generally less than 0.25%; Medium carbon steel - carbon content is generally between 0.25 and 0.60%; High carbon steel - carbon content is generally greater than 0.60%. 　　Domestic and international correspondence of 20 # steel plate: refer to the corresponding steel grade: China's GB/JB standard steel grade is 20, China's Taiwan CNS standard steel grade S20C, Germany's DIN standard material number 1.0402, Germany's DIN standard steel grade CK22/C22. British BS standard steel grade IC22, French AFNOR standard steel grade CC20, French NF standard steel grade C22, Italian UNI standard steel grade C20/C21, Belgian NBN standard steel grade C25-1, Swe...
