Q235qC Q235qD Material H Beam
Q235qC Q235qD Steel Beam H
Q235qC steel beam h and Q235qD h profile steel are carbon steel structural steel, belonging to bridge steel, is 0 degree impact; Q235QD grade is -20 degree impact; Q235QE grade is -40 degree impact. At different impact temperatures, the impact values are different.
Q235qC h beam profile and Q235qD h beam profile uses and properties.
Used to build railroads, highway bridges, cross-sea bridges with steel plate. Requirements for high strength, toughness, and to withstand the load and impact of rolling stock, and to have good fatigue resistance, a certain degree of low-temperature toughness and atmospheric corrosion resistance. Tethered welding bridge steel should also have good welding performance and low notch sensitivity.
