Q355E steel plate and Q345E steel plate

 Q355E steel plate and Q345E steel plate

　　Q355E steel plate belongs to low alloy high strength structural steel. Among them, "Q" means the yield strength, and 355 means that the yield strength of this steel is 355MPa, and the yield value will decrease as the thickness of the material increases. Regular thickness 30-300MM, width 2000-2800MM, special width and length can be customized in batches.

　　Q355E steel plate standard: GB/T1591—2018

　　Introduction to the difference between Q355E steel plate and Q345E steel plate:

　　The main difference between Q345E and Q355E materials is that Q345E limits the heat treatment process of the material and must be normalized or normalized rolling. Q345E has no special requirements. It can be said that Q355E is a steel grade extended from Q345E, and Q355E is normalized rolling at low temperature. Steel plate, higher yield than Q345E.

　　The above is the introduction, standard and difference between Q355E steel plate and Q345E steel plate. If you want to know other steel information, you can comment or private message the editor, and the editor will reply in time.

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...
