S700MC (Thermomechanically Rolled High-Strength Structural Steel) S700MC is a high-strength, low-alloy structural steel grade produced by thermomechanical rolling as per EN 10149-2 standards. Designed for cold forming applications, this steel offers a minimum yield strength of 700 MPa, making it suitable for components that demand excellent strength-to-weight ratio, durability, and fatigue resistance. Its fine-grain microstructure allows for exceptional formability despite its high strength. This grade is widely used in automotive chassis, heavy transport systems, and load-bearing structures, where reducing weight without compromising strength is critical. Key Features: Minimum yield strength of 700 MPa, offering high structural performance Excellent cold forming ability and bendability despite high strength Outstanding weldability, enabling efficient fabrication using standard methods Consistent quality with tight tolerances and fine-grain structure Typical Mechanical Properties: Property S700MC Yield Strength ≥ 700 MPa Tensile Strength 750–950 MPa Elongation ≥ 10–14% (depending on thickness) Impact Resistance High (tested at -20°C or lower) Weldability Excellent Common Applications: Automotive frames and chassis components Crane booms and lifting equipment Trailer structures and transport vehicles Agricultural machinery and structural reinforcements High-load bearing welded structures in lightweight designs Summary: S700MC is a high-strength, formable steel ideal for industries requiring lightweight yet high-load-bearing components. It allows for design optimization, reduced material consumption, and enhanced structural efficiency—making it a preferred choice in advanced engineering and transport applications.
