Q390P Steel: The Pillar in the Industrial Field

Q390P belongs to low - alloy high - strength structural steel, which is refined by adding a small amount of alloying elements on the basis of carbon structural steel. The reasonable proportion of alloying elements endows it with both high strength and good toughness and plasticity. When bearing large loads, it can maintain a stable structural state, not easy to deform and break, and it has excellent welding performance, which is convenient for processing and manufacturing.

It has a variety of size specifications. The thickness of the plate is generally between 5 - 120mm, which can meet the engineering requirements of different thicknesses. In terms of profiles, there are rich choices of cross - sectional shapes and sizes. Whether it is I - shaped, channel - shaped or angle steel, etc., it can accurately meet the design requirements of various building and mechanical structures.

Q390P is widely used in large - scale construction projects, such as high - rise office buildings and long - span bridges, which can provide reliable structural support for these buildings. In the field of heavy machinery manufacturing, Q390P steel is often used in the manufacturing of key components of cranes, excavators, etc., to ensure the stable and safe operation of the machinery under complex working conditions.
