 what is steel coil

　　Steel coil is a coiled steel product manufactured by rolling technology. It has certain ductility and strength characteristics, standardized and uniform size, and is widely used in industrial production, machinery manufacturing, home appliance manufacturing, and engineering road and bridge structures. Only by improving a certain strength can the safety of road bridges be put into use.

　　Steel coils are mainly composed of carbon and iron elements, and cold-rolled steel coils are mainly used in fields or scenarios such as home appliance panels, automobile manufacturing, and machinery manufacturing. The weather-resistant hot-rolled coil has high strength and durability when used in the structure of roads and bridges. It can prevent the corrosion of humid air when used in coastal scenes, and has a good structural support effect.

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...
