What is S460 Steel?

S460 steel refers to high-strength structural steels under EN 10025-3, including:

• S460N: Normalized, with 460 MPa yield strength and -20°C toughness, suited for moderate climates.
• S460NL: Normalized, with 460 MPa yield strength and -50°C toughness, ideal for cold environments.

The normalization process refines the grain structure, enhancing S460 steel’s strength and weldability. Compared to en 10025 3 s355n normalized structural steel plate, S460 offers higher strength for heavier structural demands.

S460 Steel Equivalent Grades by Standard

Gangsteel identifies S460 steel equivalent grades that align with its strength, toughness, and weldability:

Closest Equivalents

• A633 Grade D (for S460N): Matches -20°C toughness with 345 MPa yield, ideal for moderate climates.
• A633 Grade E (for S460NL): Closest for -40°C toughness and 415 MPa yield, suited for cold regions.
• Q460D (China): Aligns with S460N’s 460 MPa yield and -20°C toughness for Asian markets.

Chemical Composition Comparison

S460 steel equivalent grades share similar compositions:

Carbon Equivalent (CEV):

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

S460N’s low carbon and impurities ensure weldability, with A633 Gr D and Q460D as close matches, similar to en 10025 3 s420n normalized structural steel plate.

Mechanical Properties Comparison

S460 steel equivalent grades align in strength and toughness:

• Strength: Q460D matches S460N’s 460 MPa yield; A633 Gr D is lower (345 MPa).
• Toughness: All provide ≥27 J at -20°C, suitable for moderate climates; S460NL equivalents like A633 Gr E offer -40°C toughness.
• Thickness: S460N up to 200 mm, Q460D and A633 Gr D up to 100 mm, offering versatility 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).
• A633 Gr D: CEV ≤0.45%, similar preheating; PWHT for thicker plates.
• Q460D: CEV ≤0.46%, comparable welding properties.

S460N’s weldability is robust, with equivalents offering slight improvements due to lower CEV, similar to en 10025 3 s275n normalized structural steel plate.

Applications

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

S460 steel equivalent grades support comparable applications, ensuring durability.
