Q235B steel, Q345B steel.
1. The heavy material of the hanging tower generally uses national standard Q235B and Q345B steel, which is divided into three types: square steel, angle steel and round tube.
2. Q235B has certain elongation, strength, good toughness and castability, is easy to stamp and weld, and is widely used in the manufacture of general mechanical parts. It is mainly used for welded structural parts with high quality requirements in construction and bridge projects.
3. Q345b steel plate is an alloy steel material with relatively low carbon content. Its steel impact resistance grade is B level, and the steel yield value is about 345 MPa. It not only has good comprehensive performance, and has good weldability, low temperature resistance and cold stamping properties, and is easy to be cut. At the same time, its yield value can become smaller as the thickness of the steel increases, so it is widely used in the shipbuilding industry, construction industry, bridges industry, vehicle industry, pressure vessel industry, etc.
