What is S460N Steel?

S460N is a normalized or normalized rolled fine-grain 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 ASTM Equivalent Grade

Gangsteel identifies ASTM A633 Grade D as the closest S460N steel equivalent ASTM, with key considerations:

• A633 Grade D: Matches S460N’s -20°C toughness but has a lower yield strength (345 MPa vs 460 MPa), making it a partial equivalent for less demanding applications.
• Other ASTM Options: A572 Grade 65 (yield ~450 MPa) is closer in strength but lacks matching toughness specifications, making A633 Grade D the better fit.

For colder climates, S460NL’s ASTM equivalent is A633 Grade E (-40°C toughness, 415 MPa yield), as noted in en 10025 3 s460nl normalized structural steel plate.

Chemical Composition Comparison

S460N and its ASTM equivalent share similar compositions:

Carbon Equivalent (CEV):

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

S460N’s low carbon (0.20%) and impurities ensure weldability, with A633 Gr D closely matching, supported by lower sulfur and phosphorus for weld quality, similar to en 10025 3 s420n normalized structural steel plate.

Mechanical Properties Comparison

S460N and A633 Grade D align in key mechanical properties:

• Strength: S460N’s 460 MPa yield surpasses A633 Gr D’s 345 MPa, making S460N stronger for heavy loads.
• Toughness: Both provide ≥27 J at -20°C, suitable for moderate climates.
• Thickness: S460N up to 200 mm, 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.

A633 Gr D’s slightly lower CEV enhances weldability, complementing S460N’s robust weldability, 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, such as industrial frameworks and storage structures.

Both support similar applications, with S460N offering superior strength for demanding projects.
