Representation method of Japanese silicon steel belt

 Representation method of Japanese silicon steel belt

　　(1) Cold-rolled non-oriented silicon steel strip

　　From the nominal thickness (100 times the value) + code A + iron loss guarantee value (the value of the iron loss when the frequency is 50HZ and the maximum magnetic flux density is 1.5T is expanded by 100 times).

　　For example, 50A470 means a cold-rolled non-oriented silicon steel strip with a thickness of 0.5mm and a guaranteed iron loss value of ≤4.7.

　　(2) Cold-rolled grain-oriented silicon steel strip

　　From the nominal thickness (value expanded by 100 times) + code G: indicates ordinary material, P: indicates high orientation material + guaranteed value of iron loss (enlarges the iron loss value when the frequency is 50HZ and the maximum magnetic flux density is 1.7T by 100 times after the value).

　　For example, 30G130 means a cold-rolled grain-oriented silicon steel strip with a thickness of 0.3mm and a guaranteed iron loss value of ≤1.3.

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...
