Carbon Steel A105 / A105N Angles & Flats

What are Carbon Steel A105 / A105N Angles & Flats?

Carbon Steel A105 is a forged carbon steel material commonly used for piping components and structural applications. A105N refers to the normalized condition, which improves toughness and uniformity of the material. Angles and flats are structural components used in construction, fabrication, and heavy engineering applications.

Key Functions:

• Provide strong structural support
• Offer high strength and toughness
• Perform well under pressure and temperature variations
• Ensure durability in industrial environments

Chemical Composition of Carbon Steel A105 / A105N

Typical Composition:

• Carbon (C): ≤ 0.35%
• Manganese (Mn): 0.60% – 1.05%
• Silicon (Si): 0.10% – 0.35%
• Sulfur (S): ≤ 0.05%
• Phosphorus (P): ≤ 0.04%

This composition provides a balance of strength, ductility, and machinability.
