IS 2062 E350 BR / E350 C (High-Strength Structural Steel for Engineering and Fabrication) IS 2062 E350 BR and E350 C are high-strength structural steel grades categorized under the Indian Standard IS 2062. With a minimum yield strength of 350 MPa, these materials are developed for applications that demand higher mechanical strength and structural efficiency. The “BR” designation indicates the material has passed impact testing at low temperatures, while “C” specifies controlled carbon levels for better weld performance and structural integrity. These grades strike a balance between durability, workability, and cost-efficiency, making them suitable for load-intensive structures, fabrication projects, and heavy-duty industrial components. Key Features: Enhanced strength with a yield threshold of 350 MPa for high-load applications Impact-tested BR grade, suitable for colder environments and dynamic load conditions Controlled carbon content in C grade, enabling smoother welding and reducing the risk of thermal stress cracking Excellent adaptability to cutting, welding, and forming processes Typical Mechanical Properties: Property E350 BR / E350 C Yield Strength ≥ 350 MPa Tensile Strength 490–610 MPa Elongation ≥ 22% Impact Resistance BR: ≥ 27 Joules at 0°C Weldability Superior Common Applications: Steel structures for bridges, towers, and industrial buildings Equipment frameworks and machine foundations Heavy-duty trailers, vehicle chassis, and lifting devices Pressure-bearing components and fabricated assemblies General construction and structural fabrication requiring high strength Summary: IS 2062 E350 BR and E350 C are dependable choices for engineers and fabricators seeking higher strength without compromising on weldability or formability. These grades are ideal for demanding structural applications where safety, durability, and reliability are essential.
