Q355B hot rolled steel coil plate sheet
The hot rolled steel products About it
The production process of Q355B hot rolled steel coil mainly consists of the following steps: first of all, using continuous casting slab or primary rolled slab as raw material, after heating in a step heating furnace, it enters the roughing mill and finishing mill for rolling. During the rolling process, the rolling and cooling rates are controlled by computer, and finally rolled into hot rolled steel coils through the coiling machine. This production process ensures that Q355B hot rolled steel in coils have excellent physical and mechanical properties.
The chemical composition of Q355B hot rolled steel sheet in coil mainly includes carbon, silicon, manganese, sulphur, phosphorus and other elements, of which the carbon content is generally between 0.20%-0.24%, the silicon content is higher, the manganese content is in the range of 1.20%-1.60%, and the sulphur and phosphorus content is lower.
- Q355B has a tensile strength of up to 355MPa and a yield strength that meets the appropriate standards, allowing it to perform well under large loads and complex working conditions.
- Whether it is welding, cutting or bending and other processing, Q355B hot rolled steel coil can maintain good performance stability and reliability.
- The design of low alloy composition makes Q355B hot coils still maintain stable performance in harsh environments, especially suitable for offshore engineering and chemical equipment and other fields.
- This makes Q355B hot rolled steel plate easier and more reliable in forming and cold bending processes.
APPLICATIONS
Construction and bridges: Q355B hot rolled steel plate is commonly used to build structural parts for bridges and high-rise buildings due to their high strength and good welding performance.
Ships and vehicles: in ship and vehicle manufacturing, Q355B hot coils are used to make hulls and vehicle frames and other structural parts that are subject to large loads.
Pressure vessels and pipelines: due to its good corrosion resistance and low-temperature performance, Q355B hot rolled steel sheet is also widely used in the manufacture of pressure vessels and transport pipelines.
Mechanical Manufacturing: In the field of mechanical manufacturing, Q355B prime hot rolled steel coil is used to manufacture various mechanical parts and structural components, such as gears and shafts.
