 Q345qD bridge steel plate application and grade introduction

　　Q345qD belongs to the bridge structural steel plate, and the implementation standard of Q345qD steel plate is the special technical condition of GB/714.

       Q345qD steel plate grade introduction Q=yield point 345 = steel plate yield point value unit MPA q= is the bridge steel plate and the pinyin acronym of Chinese character bridge. D=steel plate grade also D also represents the steel plate is -20 degrees low temperature impact test Same as the implementation of standard bridge slabs, there are also Q235q, Q345q, Q370q, Q420q, Q460q

　　Q345qD steel plates are often used in bridge structure manufacturing, for example; Q345qD steel plates are used as raw materials for bridge equipment manufacturing, bridge structural engineering, and now cross-sea bridges, Shanghai Bridges, Shihe Bridges and Rainbow Bridges.

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...
