Gangsteel – China's Leading Mill-Direct Supplier & Exporter of S355ML Equivalent EN 10025-4 International Steel Plates
Gangsteel is the global authority for S355ML equivalent EN 10025-4 international steel plates, providing verified cross-references and direct substitutes that meet or exceed EN 10025-4 specifications while complying with ASTM, JIS, GB/T, API, and other worldwide standards. We stock over 5,000 tons of S355ML and its equivalents in thicknesses 6–200 mm, widths 1500–4200 mm, and lengths up to 18 meters, all TMCP-processed for optimal weldability and low-temperature toughness. Produced by top mills like HBIS and Shougang with full PED 2014/68/EU and CPR 305/2011 certification, our plates include EN 10204-3.1/3.2 MTCs with detailed equivalent mapping, third-party inspections from DNV-GL, ABS, Lloyd's Register, Bureau Veritas, CCS, RINA, KR, TÜV, or SGS, and Z25/Z35 through-thickness quality in stock.
S355ML's international equivalents allow seamless substitution in multinational projects, reducing procurement complexity and costs while maintaining the grade's core advantages: 355 MPa minimum yield, CEV ≤0.39 for preheat-free welding up to 80 mm, and ≥27 J Charpy V-notch at –50 °C longitudinal. Whether you're sourcing for European offshore wind, American bridge retrofits, or Asian shipyards, Gangsteel offers dual-certified plates with precise property matching. Density 7.85 g/cm³ and hardness 140-180 HBW ensure consistent performance across standards. Fast 3–7 day delivery and processing (cutting, beveling, drilling, rolling, priming) complete the service. Explore our en 10025 4 High Strength Structural Steel for the full series. For grade fundamentals, see S355ML Meaning EN 10025-4 Structural Steel Supplier.
S355ML equivalent under EN 10025-4:2004 (2019) refers to international steel grades that match or closely approximate S355ML's properties—a thermomechanically rolled (TMCP) weldable fine-grain structural steel with 355 MPa minimum yield strength and ≥27 J Charpy V-notch at –50 °C longitudinally. The designation "S355ML" means "S" for structural, "355" nominal yield (MPa, ≤16 mm transverse), "M" TMCP delivery (900-1100 °C rolling + 20-40 °C/s cooling), and "L" low-temperature impact.
Equivalents are essential for global projects, enabling substitution without re-qualification under codes like Eurocode 3 (EN 1993-1-1), DNV-OS-B101, or AASHTO. TMCP's fine grains (ASTM 8-10) and low CEV ≤0.39 provide superior weldability and isotropy versus normalized or QT alternatives, with ductility ≥22% elongation and fatigue >10^7 cycles at 160 MPa. Density 7.85 g/cm³ and hardness 140-180 HBW are consistent across equivalents.
Gangsteel supplies S355ML with dual or triple certification (e.g., EN + ASTM + GB), ideal for hybrid specs. For chemical basis, S355ML Chemical Composition EN 10025-4 Supplier; for mechanical, S355ML Mechanical Properties EN 10025-4 Plate Supplier.
Equivalents share similar chemistry; S355ML tight for TMCP.
