The chemical composition of this steel is also strictly controlled within a certain range to ensure the consistency and stability of its material. Its chemical composition includes:

C：≤ 0,10

Si：≤ 0,50

Mn：≤ 0,50

P：≤ 0,030

S：≤ 0,030

Al：≥ 0,015

The hot rolling chemical composition refers to the chemical composition requirements that the steel needs to meet during the hot rolling manufacturing process. Hot rolling is a steel processing process that produces the required steel products by heating a billet to a high temperature and then going through processing steps such as rolling, pressing, and stretching in a rolling mill. In this process, it is very important to control the chemical composition of the steel, because different chemical compositions will affect the mechanical properties, corrosion resistance, weldability, etc. of the steel, and also affect the performance of the steel in different application fields .

Specific to this hot-rolled chemical composition, C, Si, Mn, P, S, and Al respectively represent the content limits of carbon, silicon, manganese, phosphorus, sulfur, and aluminum elements in steel. These restrictions help to ensure that the chemical composition of the steel is within a certain range, thereby ensuring the stability and consistency of the mechanical properties, corrosion resistance, weldability, etc. of the steel. For example, controlling the carbon content can affect the hardness and toughness of steel, controlling the content of phosphorus and sulfur can improve the corrosion resistance and machinability of steel, and the addition of aluminum can improve the oxidation resistance and corrosion resistance of steel.

What are the mechanical properties of BMW standard GS93032-3 HR2?

The mechanical properties of BMW standard GS93032-3 HR2 are

YS：180 bis/to 290

TS(MPa)：270 bis/to 400

EL：≥ 30

YS (Yield Strength): The value of YS ranges from 180 MPa to 290 MPa, which means that steel in this range will undergo plastic deformation under the action of external forces. A higher YS value indicates a material that is stronger, more resistant to bending, and less deformable. A lower YS value means that the steel is more prone to plastic deformation, but it also means that the steel is easier to work and shape.

TS (tensile strength): The value of TS ranges from 270 MPa to 400 MPa, which means the maximum stress value that steel in this range can withstand under tensile force. A higher TS value indicates that the material has higher strength and stiffness and is able to withstand higher loads. A lower TS value means that the material is less strong, but it also means that the material is easier to form and process.

EL (elongation): The value of EL is greater than or equal to 30%, which means that steel in this range has high plasticity and toughness, and can undergo plastic deformation instead of breaking immediately when subjected to high loads. A higher EL value indicates better processability and formability of the material, but may also affect its strength and hardness.
