EN10025-4 S275ML is a fine-grained structural steel plate grade with a nominal yield strength of 275 MPa, designed to withstand a variety of harsh environments and conditions. This grade is part of the European standard for hot-rolled structural steel products and is particularly known for its excellent toughness and weldability, even at low temperatures.

Chemical Composition:

The chemical composition of S275ML is strictly controlled to ensure the required mechanical properties and weldability. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.16%

· Silicon (Si): ≤ 0.50%

· Manganese (Mn): ≤ 1.60%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.015%

· Aluminum (Al): ≥ 0.020%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.10%

· Nitrogen (N): ≤ 0.012%

· Copper (Cu): ≤ 0.30%

· Nickel (Ni): ≤ 0.30%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.08%

· Boron (B): ≤ 0.005%

Mechanical Properties:

The mechanical properties of S275ML are as follows:

· Yield Strength: ≥ 275 MPa

· Tensile Strength: 430 - 560 MPa

· Elongation: ≥ 22%

· Impact Energy (Longitudinal): ≥ 27 J at -50°C

Thermal Treatment:

S275ML plates are supplied in the thermomechanically rolled condition (M), which provides a fine-grained microstructure and enhanced mechanical properties. The plates do not require further heat treatment before or after welding, making them suitable for immediate use in fabrication.

Low-Temperature Impact Test:

The grade is tested for its toughness at low temperatures, ensuring that it meets the required impact values at -50°C. This makes S275ML particularly suitable for applications in cold climates and offshore structures.

Available Dimensions:

TJC Steel Group offers S275ML plates in a wide range of sizes, with thicknesses typically ranging from 6mm to 200mm, widths up to 4000mm, and lengths up to 18000mm. Custom sizes are also available upon request to meet specific project requirements.

Main Applications:

S275ML is widely used in various industries due to its excellent mechanical properties and weldability. Some of the primary applications include:

· Construction of bridges

· Buildings and other structures

· Offshore structures

· Pressure vessels

· Wind towers

· Heavy machinery components
