EN10025-4 S460M is a fine-grained structural steel plate grade with a nominal yield strength of 460 MPa, designed to meet the specific requirements of various industries that demand high strength and excellent toughness at low temperatures. This grade is particularly favored for its superior mechanical properties and weldability, making it suitable for a wide range of applications.

Chemical Composition:

The chemical composition of S460M is strictly controlled to ensure the material's mechanical properties and weldability. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.18%

· Silicon (Si): ≤ 0.60%

· Manganese (Mn): ≤ 1.70%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.020%

· Aluminum (Al): ≥ 0.020%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.12%

· Nitrogen (N): ≤ 0.015%

These elements are balanced to provide the necessary strength and toughness while maintaining good weldability characteristics.

Mechanical Properties:

The mechanical properties of S460M are as follows:

· Yield Strength: ≥ 460 MPa

· Tensile Strength: 540 - 720 MPa

· Elongation: ≥ 17%

· Impact Energy : ≥ 27 J

These properties are achieved through thermo-mechanical rolling, which refines the grain structure and enhances the material's performance.

Heat Treatment:

S460M is supplied in a normalized or normalized rolled condition. This heat treatment process ensures that the steel has a uniform microstructure and mechanical properties throughout the thickness of the plate.

Low-Temperature Impact Test:

S460M is subjected to a Charpy V-notch impact test at -20°C, ensuring that the material maintains its toughness and impact resistance in cold environments. The minimum impact energy is specified as 27 Joules to guarantee the material's performance in low-temperature applications.
