What is S460N Steel?

S460N is a high-strength structural steel under EN 10025-3, with:

• S: Structural steel.
• 460: Minimum yield strength of 460 MPa (≤16 mm).
• N: Normalized, with impact toughness tested at -20°C.

Its fine-grain microstructure ensures high strength and weldability, ideal for moderate climates. Compared to en 10025 3 s355n normalized structural steel plate, S460N provides higher strength for heavier structural loads.

S460N Alternative Materials by Standard

Gangsteel identifies S460N alternative materials that closely match its strength, toughness, and weldability:

Closest Alternatives

• Q460D (China): Matches S460N’s 460 MPa yield and -20°C toughness, ideal for Asian projects.
• S460M (EN 10025-4): Offers similar strength with enhanced formability and -50°C toughness.
• A633 Grade D (ASTM): Close match for -20°C toughness, though with lower yield (345 MPa).

Chemical Composition Comparison

S460N and its alternatives share similar compositions:

Carbon Equivalent (CEV):

• S460N: ≤0.48% (≤63 mm).
• Q460D: ≤0.46%.
• A633 Gr D: ≤0.45%.

Q460D’s lower sulfur (0.015%) enhances weldability, making it a strong S460N alternative, similar to en 10025 3 s420n normalized structural steel plate.

Mechanical Properties Comparison

S460N and its alternatives align in key properties:

• Strength: Q460D matches S460N’s 460 MPa yield; A633 Gr D is lower (345 MPa).
• Toughness: Q460D’s ≥34 J at -20°C slightly outperforms S460N’s ≥27 J; A633 Gr D matches S460N.
• Thickness: S460N and Q460D up to 200 mm, A633 Gr D up to 100 mm, versatile like en 10025 3 s355n normalized structural steel plate.

Welding and Heat Treatment

• S460N: CEV ≤0.48%, preheating 100-150°C for >20 mm; PWHT optional (550-650°C). Consumables: ER70S-6 (GMAW), EM12K flux with EH14 wire (SAW).
• Q460D: CEV ≤0.46%, similar preheating; PWHT for thicker plates.
• A633 Gr D: CEV ≤0.45%, comparable welding properties.

Q460D and A633 Gr D offer slightly better weldability due to lower CEV, similar to en 10025 3 s275n normalized structural steel plate.

Applications

• S460N: Bridges, cranes, building frameworks in moderate climates.
• Q460D: Similar structural uses in Asian markets, e.g., high-rise buildings.
• A633 Gr D: Structural components in temperate conditions.

S460N alternatives support comparable applications, with Q460D ideal for Asian sourcing.
