What is Steel S460N?

Steel S460N is a high-strength structural steel under EN 10025-3, with a minimum yield strength of 460 MPa for plates up to 16 mm thick. Its designation, also known as material number 1.8901, breaks down as:

• S: Structural steel.
• 460: Minimum yield strength in MPa.
• N: Normalized or normalized rolled, tested for impact toughness at -20°C.

The normalization process refines the grain structure, enhancing steel S460N’s strength, toughness, and weldability, making it ideal for moderate climates. Compared to en 10025 3 s355n normalized structural steel plate, S460N offers higher strength for heavier structural demands.

Chemical Composition Supporting Steel S460N Applications

Gangsteel ensures steel S460N meets EN 10025-3 chemical composition standards to support its applications:

Key Elements:

• Low Carbon: 0.20% max ensures clean welds and toughness.
• Manganese: 1.00-1.70% boosts strength for heavy structures.
• Aluminum & Niobium: Refine grains for toughness, critical for steel S460N applications.
• Low Sulfur & Phosphorus: Minimize inclusions for superior weld quality.

The Carbon Equivalent (CEV) is capped at 0.48% for plates up to 63 mm, calculated as CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15, ensuring weldability, similar to en 10025 3 s420n normalized structural steel plate.
