What is S275M Steel Properties EN 10025-4 Data Sheet?

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).

Applications & Design Considerations for S275M

S275M's TMCP simplicity suits Eurocode 3, trimming 10% vs. S235 in frames while padding impacts. Key fields:

• Light Infra: Walkway trusses, wind braces—KV at –20 °C bars snaps.
• Marine Lite: Dock fenders, wave barriers; fatigue EN 1993-1-9 > S235 (Δσ=140 MPa).
• Agri Mods: Farm silos, chiller frames—low CEV seals lap welds.
• Temp Mods: Seasonal sheds, expo halls; Z35 stops cracks in clips.

Tips: Use E42xx fillers; heat ≤1.8 kJ/cm HAZ. Form 1.8t cold; heat 700–850 °C. Green: 100% recycle, 15% CO2 drop vs. HR TMCP. Gangsteel does plasma cuts (±1.5 mm) and zinc (35 µm) for fixings.
