Introduction to $20$mm ST37 Hot Rolled Plate

ST37 steel is one of the world’s most recognized low-carbon structural steels, produced according to DIN $17100$ and EN $10025$ standards. Due to its balanced chemical composition and proper structure, this steel possesses desirable mechanical properties such as adequate tensile strength, high flexibility, and excellent formability and weldability.

The $20$mm hot rolled plate falls into the medium-to-heavy thickness category of steel plates and is utilized in a vast array of industrial and construction projects. This thickness strikes a perfect balance between strength and weight, making it an ideal choice for manufacturing structures, industrial equipment, and heavy metal components.

Technical Specifications of ST37 Steel Plate

ST37 steel plates possess specific technical characteristics that have led to their widespread application across various industries.

Mechanical Properties:

• Yield Limit: Minimum $235$ MPa
• Tensile Strength: $360$ to $510$ MPa
• Elongation Percentage: Approximately $20\%$
• Weldability: Highly suitable

Approximate Chemical Composition:

• Carbon ©: Maximum $0.20\%$
• Manganese (Mn): $0.35\%$ to 0.65%
• Silicon (Si): 0.15% to $0.35\%$
• Phosphorus (P): Maximum 0.045%
• Sulfur (S): Maximum 0.045%

This chemical composition ensures that the ST37 steel plate, in addition to adequate resistance, offers excellent flexibility and machinability.

ST37 Steel Plate Production Process (Hot Rolling)

The ST37 hot rolled plate is produced using the hot rolling process. Working in tandem with every major hot rolled steel plate manufacturer, we ensure the highest production standards. In this method, the steel billet/slab is heated at high temperatures and passed through rolling mill stands until its thickness is reduced to the desired value.

Main production steps include:

1. Melting steel and producing billets or slabs.
2. Heating to a temperature of about $1100$ to $1200$ ∘C.
3. Passing through rolling stands.
4. Reducing thickness down to $20$mm.
5. Controlled cooling and cutting to required dimensions.

This production method ensures the steel plate has a uniform structure, adequate resistance, and reliable quality.

Weight Table for $20$mm ST37 Hot Rolled Plate

The weight of the steel plate is calculated based on the density of steel ($7850$ kg/m3^33). The weight of each square meter of a $20$mm hot rolled plate is approximately $157$ kg.

Weight Table for Common Dimensions:

• 1×2 meters Plate: $\to$ Approx. $314$ kg
• $1.5\times 3$ meters Plate: $\to$ Approx. $706$ kg
• $2\times 6$ meters Plate: $\to$ Approx. 1884 kg

Knowing the exact weight of the hot rolled plate is highly important for calculating transportation costs, structural design, and precise project estimation.
