Gangsteel – China's Leading Mill-Direct Supplier & Exporter of S275M Steel Properties EN 10025-4 Data Sheet Plates
Gangsteel is your definitive source for S275M steel properties EN 10025-4 data sheet plates, providing 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), S275M's properties—minimum yield strength of 275 MPa, tensile range 370-530 MPa, elongation ≥24%, and impact toughness ≥40 J at –20 °C longitudinal—make it the benchmark for entry-level high-strength structural applications. We stock over 5,000 tons of S275M 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.
S275M 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 ≤0.38 ensures preheat-free welding to 100 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, S275M Meaning EN 10025-4 Structural Steel Supplier.
The S275M 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, "275" nominal yield 275 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 ≤0.38—yield superior weldability (no preheat to 100 mm), ductility (≥24% elongation), and fatigue life (>10^7 cycles at 140 MPa). Data sheets verify ReH 275 MPa min (actual 285-315 MPa typical), Rm 370-530 MPa, and KV per EN ISO 148-1 (10x10x55 mm, sub-size >40 mm). Density 7.85 g/cm³ and hardness 130-170 HBW support FEA (bilinear 2% hardening) and machining (0.2-0.3 mm/rev feeds).
S275M mechanical properties enable 5-10% thinner sections than S235JR under Eurocode 3, with partial factor γM0 = 1.0. Gangsteel data sheets are heat-traceable, supporting DNV-OS-B101 or AASHTO with CTOD (>0.3 mm at –20 °C) and KIc (>130 MPa√m at –20 °C).
