E350 Steel

IS 2062 E350, widely known as E350 steel, is a high-strength structural steel grade specified by Indian Standards. With a minimum yield strength of 350 MPa and excellent weldability, it is suitable for demanding applications including heavy construction, mining, and shipbuilding. Available in plates, beams, and other structural forms, it is versatile and reliable.

Key Features

• High Strength: Yield strength 350 MPa, tensile strength 490 MPa.
• Weldability: Easily welded with standard processes.
• Corrosion Resistance: Good general resistance to corrosion.
• Ductility & Formability: Can be shaped into complex structures.

Specifications & Variants

• IS 2062: Indian standard for hot-rolled medium and high-tensile structural steel.
• Sub-Grades: E350A, E350BR, E350BO, E350C. “E” = semi-killed steel; letters indicate impact test requirements, e.g., “C” mandates testing at -20°C.

Common Applications

• Construction: Bridges and high-rise buildings.
• Manufacturing: Heavy machinery and industrial components.
• Mining: Structural elements and mining equipment.
• Shipbuilding: Marine structures requiring strength and corrosion resistance.
