IS 2062 E450 BR / E450 C (High-Strength Steel for Advanced Structural Applications) IS 2062 E450 BR and E450 C are high-yield structural steel grades developed under the IS 2062 specification, engineered for heavy-duty and high-load applications. Offering a minimum yield strength of 450 MPa, these steels provide the strength needed for large-scale infrastructure and critical industrial structures. The BR designation ensures the material is impact-tested at low temperatures, while the C variant features controlled carbon composition to optimize weldability and toughness. These grades are ideal for applications where both mechanical performance and fabrication efficiency are key, especially in demanding structural and industrial environments. Key Features: Minimum 450 MPa yield strength, offering exceptional load-bearing capacity BR Grade meets impact resistance requirements at 0°C for improved safety C Grade features reduced carbon for better welding performance and fewer defects Reliable performance during forming, cutting, and welding operations Typical Mechanical Properties: Property E450 BR / E450 C Yield Strength ≥ 450 MPa Tensile Strength 570–720 MPa Elongation ≥ 17% Impact Resistance BR: ≥ 27 Joules at 0°C Weldability High Common Applications: Long-span bridges and tall structural frames Heavy industrial platforms and machinery bases Offshore rigs, wind towers, and structural supports Equipment like cranes, lifters, and large trailers High-strength structures requiring durable and safe performance Summary: IS 2062 E450 BR and E450 C offer a high-strength solution for structural applications demanding both durability and weldability. Trusted in critical engineering environments, they provide long-term structural reliability and performance in dynamic and high-load conditions.
