Gangsteel – China's Leading Mill-Direct Supplier & Exporter of S355ML Data Sheet EN 10025-4 Steel Properties Plates

Gangsteel is your definitive source for S355ML data sheet EN 10025-4 steel properties plates, providing downloadable data sheets with verified, heat-specific properties to accelerate your engineering, procurement, and compliance processes. As a thermomechanically rolled (TMCP) weldable fine-grain structural steel under EN 10025-4:2004 (2019 revision), S355ML's data sheet details minimum yield strength of 355 MPa, tensile range 470-630 MPa, elongation ≥22%, and low-temperature toughness ≥27 J at –50 °C longitudinal—critical for high-load, cold-environment structures. We stock over 5,000 tons of S355ML plates in thicknesses 6–200 mm, widths 1500–4200 mm, and lengths up to 18 meters, produced by premium mills like HBIS and Shougang with full PED 2014/68/EU and CPR 305/2011 certification. Each plate includes EN 10204-3.1/3.2 MTCs with full data sheet values, third-party inspections from DNV-GL, ABS, Lloyd's Register, Bureau Veritas, CCS, RINA, KR, TÜV, or SGS, Z25/Z35 through-thickness, and 100% UT EN 10160 S2/E2 testing.

S355ML data sheets from Gangsteel include spectrographic chemistry, tensile/yield/elongation per EN ISO 6892-1, Charpy V-notch per EN ISO 148-1 (sub-size for thick plates), hardness (HBW), density (7.85 g/cm³), and optional CTOD/KIc for fracture mechanics. At CEV ≤0.39, preheat-free welding to 80 mm is standard. Gangsteel data sheets support FEA under Eurocode 3 (EN 1993-1-1) with bilinear stress-strain (2% hardening), fatigue S-N curves (>10^7 cycles at 160 MPa), and buckling reduction (χ) for 15-20% weight savings vs S355J2. Fast 3–7 day delivery and processing (cutting, beveling, drilling, rolling, priming). Download sample data sheet or request heat-specific PDF.

What is S355ML Data Sheet EN 10025-4 Steel Properties?

The S355ML data sheet under EN 10025-4:2004 (2019) is the official technical document detailing all verified properties of this TMCP weldable fine-grain structural steel, where "S" means structural, "355" nominal yield 355 MPa (transverse ≤16 mm), "M" TMCP delivery, "L" –50 °C ≥27 J KV. Data sheets include ladle/product chemistry, mechanicals (yield, tensile, elongation, impact), physicals (density, hardness), and optional extras (Z-quality, CTOD).

TMCP—900-1100 °C rolling + 20-40 °C/s cooling—refines ferrite-bainite with microalloying (Nb/V/Ti), achieving ASTM 8-10 grains for isotropy. Data sheets verify CEV ≤0.39 for WPS (no preheat to 80 mm), density 7.85 g/cm³ for mass, hardness 140-180 HBW for machining. Yield governs allowable stress (f_y = ReH/γ_M0, γ_M0=1.0 Eurocode 3), with actual ReH 365-395 MPa typical. Impact per EN ISO 148-1 (10x10x55 mm, sub-size >40 mm) ensures DBTT < –60 °C.

Gangsteel data sheets are heat-traceable, supporting DNV-OS-B101 or AASHTO with CTOD (>0.4 mm) and KIc (>140 MPa√m at –40 °C). For chemical, S355ML Chemical Composition EN 10025-4 Supplier; mechanical, S355ML Mechanical Properties EN 10025-4 Plate Supplier.
