The steel plate refers to a material made of several pieces of steel by hot rolling, cold rolling or hot-dip galvanizing and welding. The steel plate is generally divided into thin plate, medium plate and hot rolled thin plate. The thin steel plate is mainly used to make mechine parts and can also be used to make molds and tools. Medium-thick steel plates are used in the construction of large buildings, bridges and engineering structures. Hot-rolled thin plates are mainly used for welding structures and are used less frequently in images.
High-quality carbon structure steel hot-rolled thick steel plates and wide steel bands (GB 711-88) are carbon structure steels, commonly referred to as strength steels, which are mainly used to manufacture parts of coal machines, vessels, bridges and engineering structures that bear greater loads and work under severe conditions. The main component is carbon steel, which contains a certain amount of alloy elements. According to the different requirements, the following are the most commonly used high-quality carbon structure hot-rolled thick steel plate and wide steel band.
Q235B, Q345B steel plate are commonly used in the market. Q235B steel plate is used to make various mechanical components, small and medium-sized welded structures, bridges and other frequently used engineering structures. Q345B steel plate is a low-alloy steel plate that is generally used to manufacture large welded structures such as ships and bridges. The following are important parameters of Q235B steel plate and Q345B steel plate.
Q235B steel plate: The yield strength of Q235B steel plate is 235Mpa, the tensile strength is 375-460Mpa, the elongation is greater than or equal to 22%, and the impact absorption energy is 27J.
Q345B steel plate: the yield strength of Q345B steel plate is no less than 345Mpa, the tensile strength is 470-630Mpa, the elongation is greater than or equal to 21%, and the impact absorption energy is 27J.
The surface quality of high-quality carbon structure hot-rolled thick steel plate and wide steel band (GB 711-88) and the surface quality requirements of the product should meet the requirements of the product structural strength and use conditions. The surface quality requirements are mainly divided into surface quality and layer quality. The requirements for surface quality include shape, roughness, parallelism, thickness deviation and folding, the requirements for layer quality include layers, inclusions and plate structure.
