Q355 h beam
Mild Steel Beam Products Description
The low alloy components of H beam steel Q355 mainly include carbon, silicon, manganese, phosphorus, sulfur, and a small amount of alloying elements such as vanadium, titanium, niobium, etc. The addition of these alloying elements not only increases the strength of the steel but also improves its toughness, weldability, and corrosion resistance. By controlling the types and contents of alloying elements, H-beam steel can be produced to meet different usage requirements.
In terms of production technology, H beam steel Q355 usually adopts hot rolling forming technology. This technology can heat the steel to a certain temperature and then roll it to obtain the ideal cross-sectional shape and dimensional accuracy. Hot-rolled H-beam steel has the characteristics of good surface quality, precise dimensions, high strength, and easy welding, so it has been widely used in construction, bridges, and other fields.
In addition to the material and production process, H-beam steel Q355 also has good weldability. This is due to its low alloy composition and appropriate carbon equivalent. In actual projects, H-beam steel Q355 can be connected through various welding methods, such as manual arc welding, submerged arc welding, gas-shielded welding, etc. At the same time, its welded joints also have high strength and toughness, ensuring the safety and stability of the structure.
The chemical composition of Q355 steel is shown in the table below:
| Steel Grade | Quality Grade | C % (≤) | Si % (≤) | Mn (≤) | P (≤) | S (≤) | Cr (≤) | Ni (≤) | Cu (≤) | N (≤) |
