EN10025-2 S355K2 is a non-alloy structural steel plate widely recognized for its excellent mechanical properties and versatile applications across various industries. This grade is part of the European standard for hot-rolled structural steel, and it is particularly appreciated for its high strength and durability.

Chemical Composition:

The chemical composition of S355K2 is strictly controlled to ensure the material's mechanical properties and weldability. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.20%

· Silicon (Si): ≤ 0.55%

· Manganese (Mn): ≤ 1.60%

· Phosphorus (P): ≤ 0.035%

· Sulfur (S): ≤ 0.035%

· Copper (Cu): ≤ 0.55%

· Nickel (Ni): ≤ 0.55%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.10%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.05%

· Vanadium (V): ≤ 0.12%

Mechanical Properties:

The mechanical properties of S355K2 are as follows:

· Yield Strength: ≥ 355 MPa

· Tensile Strength: 470 - 630 MPa

· Elongation: ≥ 22%

· Impact Energy (at -20°C): ≥ 27J

Heat Treatment State:

S355K2 is generally supplied in the normalised condition. Normalising involves heating the steel to a temperature above its upper critical point and then cooling in air. This process refines the grain structure and improves the mechanical properties, particularly toughness.

Low-Temperature Impact Test:

The material is tested for its impact resistance at -20°C, ensuring that it maintains its toughness and strength in cold environments. This is particularly important for applications in areas with low temperatures.

Available Dimensions:

TJC Steel Group can supply S355K2 structural steel plates in a wide range of sizes, with thicknesses ranging from 6mm to 300mm, widths up to 4000mm, and lengths up to 18000mm. Custom sizes are also available upon request to meet specific project requirements.

Main Applications:

S355K2 is used in a variety of applications due to its excellent strength and toughness, including:

· Construction of bridges and other large structures

· Offshore structures

· Power plants

· Mining and earth-moving equipment

· Load-bearing parts for mobile equipment
