IS 2062 E350A/BR/BO/C

IS 2062 E350 is a high-tensile structural steel widely used in construction and engineering applications due to its superior mechanical properties, strength, and versatility. Governed by the Bureau of Indian Standards (BIS), this steel grade is categorized into different sub-grades to meet specific application requirements: E350A, E350BR, E350BO, and E350C.

Key Characteristics

• High Tensile Strength: IS 2062 E350 steel provides a minimum yield strength of 350 MPa, ensuring robust performance under heavy loads.
• Good Weldability: This steel grade offers excellent weldability, allowing for easy fabrication and assembly.
• Enhanced Toughness: The steel's composition ensures good toughness, making it suitable for use in harsh environments and dynamic loading conditions.

Chemical Composition

The typical chemical composition of IS 2062 E350 steel includes:

• Carbon (C): ≤ 0.20%
• Manganese (Mn): 1.50% - 1.60%
• Phosphorus (P): ≤ 0.045%
• Sulphur (S): ≤ 0.045%
• Silicon (Si): ≤ 0.45%

Sub-Grades and Their Applications

E350A

E350A is the most basic grade within the E350 classification. It is used where the requirements for high tensile strength and toughness are critical but without the need for special properties such as enhanced weldability or low-temperature impact resistance.

• Applications: General construction, building frameworks, bridges, and other structures that require high-strength steel.

E350BR

E350BR (Boron Restricted) is designed to ensure better weldability by controlling the amount of boron in the steel. This makes it particularly suitable for welded structures.

• Applications: Fabrication of welded structures, including construction equipment, bridges, and pipelines where superior weldability is essential.

E350BO

E350BO (Boron) steel has a controlled addition of boron, enhancing its hardenability. This grade is suitable for applications requiring higher strength and toughness.

• Applications: Heavy-duty machinery, structural components in heavy engineering, and applications requiring high wear resistance.

E350C

E350C is a notch-toughness grade steel that provides better toughness and impact resistance, especially at lower temperatures. It is suitable for dynamic loading conditions and environments with significant temperature variations.

• Applications: Offshore structures, wind turbine towers, industrial storage tanks, and other applications requiring high toughness and impact resistance.

Advantages of IS 2062 E350 Steel

• Versatility: Suitable for a wide range of applications across various industries.
• Strength and Durability: High tensile strength and toughness ensure longevity and reliability.
• Cost-Effective: Provides a good balance between performance and cost, making it an economical choice for structural applications.
• Availability: Widely available in the market, ensuring easy sourcing and procurement.
