Gangsteel – China's Leading Mill-Direct Supplier & Exporter of S355M Properties EN 10025-4 Data Sheet Steel Plates
Gangsteel is your definitive source for S355M properties EN 10025-4 data sheet steel plates, delivering downloadable, heat-specific data sheets with verified mechanical, chemical, and physical properties for precise engineering and compliance. As a thermomechanically rolled (TMCP) weldable fine-grain structural steel under EN 10025-4:2004 (2019 revision), S355M's properties—355 MPa minimum yield strength, tensile range 470-630 MPa, elongation ≥22%, and impact toughness ≥40 J at –20 °C longitudinal—make it the reliable choice for high-strength applications above –20 °C. We stock over 4,000 tons of S355M 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 complete 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 options, and 100% UT EN 10160 S2/E2 testing.
S355M data sheets from Gangsteel include spectrographic chemistry, tensile/yield/elongation per EN ISO 6892-1, Charpy V-notch per EN ISO 148-1, hardness (HBW), density (7.85 g/cm³), and optional CTOD for fracture mechanics. CEV ≤0.39 ensures preheat-free welding to 80 mm. Fast 3–7 day delivery and processing (cutting, beveling, drilling, rolling, priming). Download sample data sheet or request heat-specific PDF. Explore our en 10025 4 High Strength Structural Steel series. For grade overview, S355M Meaning EN 10025-4 Structural Grade Supplier.
The S355M 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 (900-1100 °C rolling + 20-40 °C/s cooling). Data sheets include ladle/product chemistry, mechanicals (yield, tensile, elongation, impact), physicals (density, hardness), and optional extras (Z-quality, CTOD).
TMCP's properties—low residual stress (<100 MPa), fine grains (ASTM 8-10), and CEV ≤0.39—yield superior weldability (no preheat to 80 mm), ductility (≥22% elongation), and fatigue life (>10^7 cycles at 160 MPa). Data sheets verify ReH 355 MPa min (actual 365-395 MPa typical), Rm 470-630 MPa, and KV ≥40 J at –20 °C for Eurocode 3 fatigue (S-N >10^7 cycles at 160 MPa R=0.1). Density 7.85 g/cm³ and hardness 140-180 HBW support FEA (bilinear 2% hardening) and machining (0.2-0.3 mm/rev feeds).
Gangsteel data sheets are heat-traceable, supporting DNV-OS-B101 or AASHTO with CTOD (>0.35 mm at –20 °C) and KIc (>140 MPa√m at –20 °C). For chemical basis, S355M Chemical Composition EN 10025-4 Supplier; mechanical, S355M Mechanical Properties EN 10025-4 Plate Supplier.

Q1: S355M properties exact value?
A: Yield 355 MPa min ≤16 mm, derating to 285 MPa at 150-200 mm (transverse). Actual Gangsteel 365-395 MPa typical; EN ISO 6892-1 tested. Key for Eurocode 3 allowable stress (f_y = ReH/γ_M0, γ_M0=1.0).
Q2: S355M vs S355ML properties difference?
A: Impact temp: S355M –20 °C ≥40 J for temperate (bridges/machinery); S355ML –50 °C ≥27 J for cold (offshore/Arctic). Yield/chem/elong/density same—ML for < –20 °C (DNV-OS-B101). Gangsteel stocks both with properties MTCs.
Q3: Welding preheat for S355M properties?
A: None to 80 mm (CEV 0.34-0.38); low-H E7018 H4. Thicker: 75-120 °C (EN ISO 13916). TMCP low stress preserves properties; saves 50 °C vs J2; CET per heat WPS.
Q4: S355M for pressure vessels properties?
A: Yes, PED III (EN 13445); derate >63 mm. UT S3/E3; RT opt seams. Properties aid fracture (KIc >140 MPa√m); cost-effective vs QT; dual ASME/EN.
