S460 Steel Properties Overview

S460 Steel Properties Overview

At Gangsteel, we’re eager to unpack the exceptional S460 steel properties that make this high-strength, low-alloy structural steel a standout for demanding projects. S460, encompassing grades like S460N and S460NL under EN 10025-3, is normalized or normalized rolled for a fine-grain structure, delivering robust strength and toughness for applications like bridges, cranes, and offshore platforms. As part of the en 10025 3 normalized steel plate family, S460N offers -20°C toughness, while S460NL provides -50°C toughness for colder climates.

Gangsteel dives into the S460 steel properties, including chemical composition, mechanical characteristics, and applications, with comparisons to grades like en 10025 3 s420n normalized structural steel plate and en 10025 3 s355n normalized structural steel plate.

What is S460 Steel Properties?

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

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

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

Chemical Composition Supporting S460 Steel Properties

Gangsteel ensures S460 steel properties are backed by a precise chemical composition per EN 10025-3:

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, making it ideal for colder climates, similar to en 10025 3 s420n normalized structural steel plate.

Mechanical Properties of S460 Steel

S460 steel properties are optimized for high-strength applications:

• Yield Strength: 460 MPa for thin plates, ideal for heavy loads in structures like cranes.
• Tensile Strength: 540-720 MPa ensures durability under high tensile forces.
• Elongation: ≥17% supports complex structural designs.
• Impact Toughness: S460N’s ≥27 J at -20°C suits moderate climates; S460NL’s ≥27 J at -50°C excels in cold environments.
• Hardness: 170-210 HB balances machinability and durability, outperforming en 10025 3 s355n normalized structural steel plate in strength.
