What is EN 10025-3 S460NL/ML Steel?

EN 10025-3 S460NL/ML is a high-strength structural steel with a minimum yield strength of 460 MPa for plates up to 16 mm thick. The "NL" indicates normalized with -50°C toughness, while "ML" refers to the thermomechanical variant under EN 10025-4 with similar properties but better formability. Its designation breaks down as:

• S: Structural steel.
• 460: Minimum yield strength in MPa.
• NL/ML: Normalized (NL) or thermomechanically rolled (ML), both tested for impact toughness at -50°C.

This combination ensures EN 10025-3 S460NL/ML offers enhanced toughness for cold environments, with normalization refining the grain structure for strength and weldability. Compared to en 10025 3 s355nl normalized structural steel plate, S460NL/ML provides higher strength for more demanding loads.

Chemical Composition of S460NL/ML

Gangsteel ensures S460NL/ML’s chemical composition is optimized for toughness and cold-weather strength:

Key Elements:

• Low Carbon: 0.20% max ensures clean welds and toughness.
• Manganese: 1.00-1.70% boosts strength for heavy structures.
• Aluminum & Niobium: Refine grains for -50°C toughness, a key EN 10025-3 S460NL/ML feature.
• Low Sulfur & Phosphorus: Minimize inclusions for superior weld quality.

The Carbon Equivalent (CEV) is capped at 0.48% for plates up to 63 mm, ensuring easy welding, similar to en 10025 3 s420nl normalized structural steel plate.

Mechanical Properties and Enhanced Toughness

EN 10025-3 S460NL/ML mechanical properties emphasize enhanced toughness for cold climates:

• Toughness: Both deliver ≥27 J at -50°C, ensuring cold-climate reliability, but S460ML’s TMCP process may enhance grain consistency for thinner sections.
• Strength: Similar yield (460 MPa) and tensile strength (540-720 MPa), with S460ML maintaining higher yield in thicker sections.
• Elongation: ≥17% supports ductility for complex designs.
• Hardness: Typically 170-210 HB (Brinell), balancing machinability and durability.

EN 10025-3 S460NL/ML’s enhanced toughness makes it superior for sub-zero applications.

Welding and Heat Treatment

EN 10025-3 S460NL/ML is highly weldable with a low CEV (≤0.48%):

• Welding: GMAW and SAW per EN 1011-2. Preheating (100-150°C) for >20 mm; PWHT at 550-650°C optional.
• Consumables: ER70S-6 for GMAW, EM12K flux with EH14 wire for SAW.
• Weld Quality: Matches en 10025 3 s355n normalized structural steel plate for reliable, high-strength welds.
