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...
