Q355DH steel product introduction

 Q355DH steel product introduction

         1. Q355DH section steel is a new type of hot-rolled section steel, which has the advantages of shock resistance, wind resistance and impact resistance, and has relatively low requirements on the surface quality of steel.

         2. Q355DH section steel is a section steel product made of high-quality Q345AQ345B slabs smelted in electric furnace or converter, straightened by straightening machine or automatic cutting machine after heating, and then pickled and polished after cold forming. .

　　3. Q355DH section steel is generally divided into two types: hot-dip galvanized section steel and cold-dip galvanized section steel.

　　4. After the Q355DH steel is pickled, it is generally not pickled.

　　5. The strength of Q355DH steel mainly depends on the height and width of the transverse rib. In the case of the same height, the wider the width, the higher the bending strength.

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...
