Introduction to Hot - Rolled S335 Jr Carbon Steel Sheet

 

 

:

The minimum yield strength of S335 Jr steel is 335 MPa. This provides the steel with the ability to withstand significant loads without permanent deformation. The tensile strength is also an important property, usually in the range that makes it suitable for a variety of structural applications. The elongation at break indicates the ductility of the steel, allowing it to deform to a certain extent before fracturing.

Production Process of Hot - Rolled S335 Jr Carbon Steel Sheet

: The production starts with high - quality iron ore and scrap steel as the main raw materials. These are melted in a furnace, usually a basic oxygen furnace (BOF) or an electric arc furnace (EAF), depending on the production facility.

Hot - Rolling Process:

After the steel is melted and refined to the desired chemical composition, it is cast into slabs. These slabs are then reheated to the hot - rolling temperature, which is typically above 1000 degree . The hot slabs are passed through a series of rollers with decreasing diameters to gradually reduce the thickness of the steel to the desired sheet thickness. The hot - rolling process also helps to improve the microstructure of the steel, making it more uniform and improving its mechanical properties.

During hot - rolling, the steel undergoes plastic deformation, which can cause the grains to elongate in the direction of rolling. This can lead to anisotropic mechanical properties, meaning the properties may vary depending on the direction of the applied force.

Applications of Hot - Rolled S335 Jr Carbon Steel Sheet

:

In the construction industry, it is widely used for structural components such as beams, columns, and roof trusses. The high yield strength allows these components to support heavy loads, making it suitable for buildings, bridges, and industrial structures. For example, in the construction of a multi - storey building, S335 Jr steel sheets can be used to fabricate the main load - bearing columns and beams.

 

Surface Quality and Treatment of Hot - Rolled S335 Jr Carbon Steel Sheet

:

Hot - rolled S335 Jr steel sheets usually have a characteristic scale on the surface due to the oxidation that occurs during the hot - rolling process. This scale can affect the appearance and the subsequent surface treatment of the steel. The surface may also have some irregularities such as roll marks, which are impressions left by the rollers during the rolling process.
