DIN 17100 ST52 is a well-regarded structural grade steel, specifically a high-strength, low-alloy (HSLA) steel. It is designated under the German DIN standard and is known for its excellent combination of strength and toughness, making it suitable for demanding applications.
Key Mechanical Properties of ST52 Steel
ST52 steel, particularly the ST52-3 variant, exhibits notable mechanical characteristics:
- Yield Strength: Typically, the minimum yield strength for ST52-3 is around 355 MPa. This high yield strength contributes to its ability to withstand significant loads before permanent deformation occurs.
- Tensile Strength: The tensile strength for ST52-3 generally ranges from 490 MPa to 630 MPa, indicating its capacity to resist breaking under tension.
- Weldability: One of the significant advantages of ST52 steel is its good weldability. It can be readily welded using common welding processes, which is crucial for fabrication.
- Impact Strength: ST52-3 also offers good impact strength, making it reliable in various environmental conditions.
These properties make ST52 a preferred material for many structural and engineering projects. Companies like Shanxi Luokaiwei Steel Company often supply this grade with various testing and certification options.
Equivalent Standards
DIN 17100 ST52-3 has a close equivalent in European standards. The most common equivalent is S355JR under EN 10025-2. This S355JR designation indicates a structural steel with a minimum yield strength of 355 MPa and specific impact testing requirements (JR indicates impact energy testing at +20°C).
Applications of ST52 Carbon Steel Plate
Due to its favorable mechanical properties, DIN 17100 ST52 steel plate finds extensive use in a variety of sectors:
- Construction: Used in building structures, bridges, and other load-bearing components.
- Machinery Manufacturing: For manufacturing heavy machinery parts, frames, and bases.
- Automotive Industry: In the production of vehicle chassis and components requiring high strength.
- Offshore Structures: Its toughness and strength make it suitable for applications in demanding marine environments.
- General Fabrication: Due to its excellent weldability and strength.
The versatility of ST52, including material sourced from reliable suppliers such as Shanxi Luokaiwei Steel Company, ensures its continued relevance in heavy industries.
Supply and Considerations
ST52 steel plates are typically supplied in normalized or as-rolled conditions. The choice depends on the specific application requirements. When sourcing this material, it is important to ensure it meets the DIN 17100 standard specifications or its EN equivalent. Verification of material certificates from suppliers, such as Shanxi Luokaiwei Steel Company, is crucial. For specific project needs, additional treatments or testing might be requested to ensure optimal performance.
Overall, DIN 17100 ST52 steel plate is a robust and reliable material for structural and general engineering purposes, valued for its strength, weldability, and toughness. When considering ST52, consulting with experienced suppliers like Shanxi Luokaiwei Steel Company can help ensure the material meets all project specifications.
