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

Both grades feature a fine-grain microstructure for strength and weldability, with S460NL better suited for sub-zero environments. Compared to en 10025 3 s355n normalized structural steel plate, S460 offers higher strength for heavier loads.

S460 Steel ASTM Equivalent Grades

Gangsteel identifies the closest ASTM equivalents for S460 steel, focusing on strength, toughness, and weldability:

• A633 Grade D: Closest S460N equivalent, with similar -20°C toughness but lower yield strength.
• A633 Grade E: Closest S460NL equivalent, with -40°C toughness, slightly lower yield strength but excellent for cold applications.

Other ASTM grades like A572 Gr 65 (yield ~450 MPa) are less precise matches due to differing toughness requirements.

Chemical Composition Comparison

S460 steel equivalents align closely in composition:

Carbon Equivalent (CEV):

• S460N: ≤0.48% (≤63 mm).
• S460NL: ≤0.48%.
• A633 Gr D: ≤0.45%.
• A633 Gr E: ≤0.45%.

S460NL’s lower sulfur (0.020% vs 0.025%) enhances toughness, making A633 Gr E the better S460 steel equivalent ASTM for cold climates, similar to en 10025 3 s420n normalized structural steel plate.

Mechanical Properties Comparison

S460 steel equivalents align in strength and toughness:

• Strength: S460N and S460NL match at 460 MPa yield; A633 Gr D (345 MPa) and Gr E (415 MPa) are lower but viable.
• Toughness: S460NL’s -50°C toughness surpasses A633 Gr E’s -40°C, making it the closer match for cold climates; S460N aligns with A633 Gr D.
• Thickness: S460N/S460NL up to 200 mm; A633 Gr D/E up to 100 mm, comparable to en 10025 3 s275n normalized structural steel plate.

Welding and Heat Treatment

• S460N/S460NL: 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/E: CEV ≤0.45%, similar preheating; PWHT for thicker plates.

A633 grades offer slightly better weldability due to lower CEV, complementing S460N/S460NL’s robust weldability.

Applications

• S460N: Bridges, cranes, building frameworks in moderate climates.
• S460NL: Offshore platforms, wind towers in cold climates (e.g., Arctic).
• A633 Gr D: Structural components in temperate conditions.
• A633 Gr E: Cold-climate structures and pressure vessels.

S460 steel equivalents support similar applications, with A633 Gr E closer to S460NL for cold environments.

FAQ

What is the best S460 steel equivalent ASTM?
A633 Grade E is the best S460NL equivalent for -40°C toughness and 415 MPa yield; A633 Grade D suits S460N for -20°C applications.

How does S460N compare to A633 Gr D?
S460N has higher yield strength (460 MPa vs 345 MPa) and similar -20°C toughness, making it stronger for moderate climates.

How does S460NL compare to A633 Gr E?
S460NL’s -50°C toughness and 460 MPa yield surpass A633 Gr E’s -40°C and 415 MPa, but both are ideal for cold climates.

Can A572 Gr 65 replace S460 steel?
