Quality Steel S355ML/1.8834

High-strength, weldable fine-grain structural steel supplied to EN 10025-4 (material number 1.8834). S355ML is a thermo‑mechanically rolled (TMCP) structural grade designed for heavily loaded welded constructions that require good toughness at low temperatures and reliable weldability.

Key features

• Supplied in TMCP condition for improved toughness and strength consistency
• Fine-grain, low‑alloy structural steel suitable for heavy welded fabrications
• Good weldability and formability for typical structural processes
• Design service temperature down to -50°C (longitudinal impact energy warranty: 27 J)
• Note: subsequent heating above 580°C for TMCP products leads to reduced strength

Available forms and standard dimensions

• Forms: plates, sheets and bars
• Thickness range: 5 mm – 150 mm
• Width: 1,500 mm – 4,200 mm
• Length: 3,000 mm – 18,000 mm

Typical applications

• Bridges and other civil engineering structures
• Flood gates and water-retaining structures
• Storage and transport containers, tanks
• Load-bearing and welded structural components
• Pressure and pipeline components where welded construction and low-temperature toughness are required

Quality and compliance

• Manufactured and tested to EN 10025-4 (S355ML / 1.8834)
• Supplied with standard EN test documentation on request (mill certificates and impact test results as applicable)

Supply options and processing

• Available cut-to-length, sawn, shot-blasted or with further processing on request
• Supplied in full plates or nested to buyer length/width requirements

For engineering procurement, specify EN 10025-4 S355ML (1.8834), required thickness/size, required delivery condition (TMCP) and any certification or testing documentation needed.
