Steel is one of the most versatile and widely used materials in the world, serving as the backbone of countless industries ranging from construction to automotive manufacturing. Among the various forms of steel available, hot rolled steel plates stand out as a popular choice for many applications. Understanding the advantages and drawbacks of hot rolled steel plates is crucial for informed decision-making in industries that rely on this material.

Hot rolled steel plates are generally more cost-effective than their cold rolled counterparts. The hot rolling process involves heating the steel to high temperatures, which makes it easier to shape and form. This efficiency in manufacturing often translates to lower production costs, making hot rolled steel plates an attractive option for budget-conscious projects.
Hot rolled steel plates tend to possess greater strength and durability compared to cold rolled steel. The high temperatures involved in the hot rolling process alter the steel's grain structure, resulting in improved mechanical properties. This enhanced strength makes hot rolled steel plates well-suited for applications requiring robustness and resistance to wear and tear.
The hot rolling process imparts a level of malleability to steel that allows for easier shaping and forming. This characteristic makes hot rolled steel plates ideal for applications that involve complex or intricate designs. Whether it's bending, welding, or machining, hot rolled steel plates offer greater flexibility during fabrication, enabling manufacturers to create customized components with relative ease.
Hot rolled steel plates are readily available in a wide range of sizes, thicknesses, and grades to suit diverse industrial requirements. This abundance and variety make it easier for businesses to source the specific type of steel plates they need for their projects. From structural applications in construction to heavy machinery manufacturing, hot rolled steel plates offer versatility and adaptability across various sectors.
One of the primary drawbacks of hot rolled steel plates is their surface finish. The rapid cooling process after hot rolling can result in a rough, uneven surface texture characterized by mill scale and surface imperfections. While this may not affect the structural integrity of the steel, it can pose challenges in applications where a smooth or aesthetically pleasing surface is desired.
Hot rolling can lead to dimensional variations in steel plates, particularly in terms of thickness and flatness. The high temperatures and rapid cooling inherent to the process may cause some degree of distortion or warping in the final product. Achieving precise dimensional accuracy may require additional processing or machining, adding to the overall cost and complexity of production.
Although hot rolled steel plates offer excellent initial malleability, they are prone to work hardening during subsequent forming or machining operations. Work hardening occurs when the steel undergoes deformation, causing an increase in its strength and hardness. While this can be advantageous in certain applications, it may also pose challenges in processes that require extensive shaping or manipulation of the material.
Compared to cold rolled steel, hot rolled steel plates offer limited options in terms of surface finish. The inherent characteristics of the hot rolling process make it difficult to achieve smooth, polished surfaces without additional processing steps. This limitation may restrict the suitability of hot rolled steel plates for applications where aesthetic appeal or surface quality is paramount.
In conclusion, hot rolled steel plates offer a range of advantages, including cost-effectiveness, strength, malleability, and availability. However, they also come with certain drawbacks, such as surface quality issues, dimensional variations, work hardening tendencies, and limited surface finish options. Understanding these pros and cons is essential for businesses and industries that rely on hot rolled steel plates for their operations. By weighing the benefits against the limitations, stakeholders can make informed decisions regarding the suitability of hot rolled steel plates for their specific applications.

Both hot rolling and cold rolling are processes of forming steel or steel sheets, which have a great influence on the microstructure and properties of steel. The rolling of steel is mainly hot rolling, and the cold rolling is only used for producing small steel and thin steel.
1. Advantages of hot rolling: It can destroy the casting structure of steel ingot, refine the grain of steel, and eliminate the defects of microstructure, so that the steel structure is compact and the mechanical properties are improved.
This improvement is mainly reflected in the rolling direction, so that the steel is no longer an isotropic body to some extent; bubbles, cracks and looseness formed during casting can also be welded under high temperature and pressure.

Disadvantages:
1. After hot rolling, non-metallic inclusions (mainly sulfides and oxides, as well as silicates) inside the steel are pressed into thin sheets, and delamination (sandwich) occurs.
The delamination greatly deteriorates the tensile properties of the steel in the thickness direction, and it is possible that interlaminar tearing occurs when the weld is shrunk.
The local strain induced by weld shrinkage often reaches several times the yield point strain, which is much larger than the strain caused by the load;
2. The residual stress caused by uneven cooling. The residual stress is the internal self-phase equilibrium stress without external force.
The hot-rolled steel of various sections has such residual stress.
The larger the section size of the general section steel, the larger the residual stress.
Although the residual stress is self-phase-balanced, it still has some influence on the performance of steel members under external force. Such as deformation, stability, fatigue and other aspects may have adverse effects.
3. Cold rolling refers to the processing of steel sheets or steel strips into various types of steel at room temperature by cold drawing, cold bending, cold drawing and other cold working.
Advantages: fast forming speed, high output, without damaging the coating, can be made into a variety of cross-section forms to meet the needs of the use conditions; cold rolling can make the steel produce a large plastic deformation, thereby improving the yield of the steel point.
Disadvantages:
1. Although there is no hot plastic compression in the forming process, there are still residual stresses in the section, which will inevitably affect the overall and local buckling characteristics of the steel;
2. The cold-rolled steel is generally open-section, making the section free. The torsional stiffness is low. It is easy to twist when being bent, and it is prone to bending and torsion buckling when pressed, and the torsion resistance is poor.
3. The wall thickness of cold-rolled steel is small, and there is no thickening at the corner of the plate joint, which is subject to locality. The ability to concentrate loads is weak.
