S460N/NL Comparison

S460N vs S460NL Comparison

At Gangsteel, we’re here to clarify the differences between S460N vs S460NL, two high-strength, low-alloy structural steels under EN 10025-3, to help you choose the right material for your project. Both S460N and S460NL offer a fine-grain structure and 460 MPa yield strength, but S460N is tested for -20°C toughness, while S460NL excels at -50°C, making it ideal for colder climates.

As part of the en 10025 3 normalized steel plate family, both grades are normalized for consistent performance. Gangsteel compares their chemical composition, mechanical properties, and applications, with ties to grades like en 10025 3 s420n normalized structural steel plate and en 10025 3 s355n normalized structural steel plate.

Overview of S460N and S460NL

• S460N (EN 10025-3): Normalized or normalized rolled, with 460 MPa yield strength and -20°C toughness, ideal for bridges and cranes in moderate climates (e.g., temperate Europe).
• S460NL (EN 10025-3): Normalized or normalized rolled, with 460 MPa yield strength and -50°C toughness, suited for cold climates (e.g., Arctic regions or northern Europe).

Both grades share similar processing but differ in low-temperature performance, with S460NL offering superior toughness for extreme conditions.

Chemical Composition Comparison

The chemical composition of S460N vs S460NL influences their toughness:

Carbon Equivalent (CEV):

• S460N: ≤0.48% (≤63 mm).
• S460NL: ≤0.48% (≤63 mm).

S460NL’s lower sulfur (0.020% vs 0.025%) and phosphorus (0.025% vs 0.030%) enhance toughness and weldability, making it better for sub-zero climates, similar to en 10025 3 s420n normalized structural steel plate.

Mechanical Properties Comparison

S460N vs S460NL mechanical properties highlight their differences:

• Strength: Both offer 460 MPa yield strength, ideal for heavy loads in structures like bridges.
• Toughness: S460NL’s -50°C toughness (≥27 J) outperforms S460N’s -20°C, making it better for cold climates.
• Thickness: Both support up to 200 mm, versatile for structural applications like en 10025 3 s355n normalized structural steel plate.

Processing and Fabrication

• S460N: Normalized for consistent microstructure; suited for standard welding and machining. Preheating (100-150°C) for >20 mm; PWHT optional (550-650°C).
• S460NL: Normalized with stricter impurity control for enhanced toughness; similar welding requirements.

Consumables: Both use ER70S-6 (GMAW), EM12K flux with EH14 wire (SAW). S460NL’s lower impurities reduce weld imperfections.

Applications

• S460N: Bridges, cranes, and building frameworks in moderate climates (e.g., temperate regions).
• S460NL: Offshore platforms, wind towers, and bridges in cold climates (e.g., Arctic or northern Europe) due to superior low-temperature toughness.

S460NL is preferred for sub-zero conditions, while S460N suits milder environments.
