DIN 17100 RST 37-2 steel is a non-alloy structural steel grade widely utilized in construction, civil engineering, machinery manufacturing, petrochemicals, automotive, and other industries due to its balanced mechanical properties and weldability.
1. Construction and Civil Engineering
Structural Components: Used for load-bearing beams, columns, and support structures in buildings, bridges, and underground projects (e.g., subways and tunnels).
Foundation Work: Suitable for piles, anchor bolts, and other foundation elements requiring high strength and stability.
2. Machinery Manufacturing
Mechanical Parts: Employed in the fabrication of shafts, gears, and other components requiring moderate strength and toughness.
Industrial Equipment: Used in manufacturing frames, brackets, and structural parts for machinery, ensuring durability under operational stresses.
3. Petrochemical Industry
Pressure Vessels and Pipelines: Suitable for low-pressure vessels and pipelines in non-critical petrochemical applications, offering corrosion resistance and structural integrity.
4. Automotive Industry
Vehicle Components: Utilized in the production of chassis parts, brackets, and other structural elements requiring moderate strength and formability.
5. General Engineering Applications
Bolted and Welded Structures: Ideal for fabrications requiring welding, bolting, or riveting, such as agricultural machinery, mining equipment, and transmission towers.
Key Characteristics Supporting These Applications
Mechanical Properties: Balanced yield strength (≥215 MPa) and tensile strength (340–470 MPa) ensure structural reliability.
Weldability: Facilitates easy fabrication through welding processes.
Corrosion Resistance: Provides adequate protection in non-aggressive environments, extending service life.
This steel grade’s versatility and cost-effectiveness make it a preferred choice for applications where high-performance alloys are unnecessary, offering a reliable solution for general structural and mechanical needs.
