As a seasoned Chinese steel exporter dedicated to empowering global builders with dependable materials, Gangsteel stocks premium en 10025 4 s275ml steel plate from our expansive 15,000+ ton inventory. EN 10025-4 S275ML is a foundational high-strength, fine-grain structural steel developed through TMCP (Thermomechanical Controlled Processing), offering a minimum yield strength of 275 MPa and reliable low-temperature toughness to -50°C. Available in thicknesses 6–200 mm, widths up to 4200 mm, and lengths to 18 m, our plates are manufactured by top mills like HBIS and Baowu, complete with PED/CE marking (2014/68/EU) and EN 10204-3.1/3.2 test reports. Third-party validations from DNV, ABS, Lloyd’s, BV, or TÜV ensure seamless integration into international standards.

What is EN 10025-4 S275ML TMCP Structural Steel Plate?

EN 10025-4 S275ML is a thermomechanically rolled (TMCP) weldable fine-grain structural steel specified in the European EN 10025-4:2004 standard (updated 2019), designed for economical strength in cold-prone settings. The "S" denotes structural purpose, "275" the nominal yield in MPa for thin gauges, "M" the thermomechanical state, and "L" enhanced impact at -50°C (≥27J Charpy V-notch). TMCP—controlled deformation and cooling—forms a consistent ferrite structure, yielding 5–10% better performance than S235JR or S275J0 in EN 10025-2, with 8–12% thinner sections for lighter footprints.

Core strengths include low carbon equivalent (CEV ≤ 0.38) for welding without preheat up to 100 mm thick, strong HAZ crack resistance, and optional Z-direction (Z25/Z35) to avoid delamination in joints. Unlike normalized EN 10025-3 S275NL, S275M's TMCP reduces stresses and improves uniformity for mild dynamics. It meets Eurocode 3 and EN 1090 for fabrication, powering from refrigerated warehouses to basic marine aids. Gangsteel focuses on S275ML stock (key 10–70 mm thick) for fast 3–7 day delivery, supporting ventures like Nordic storage and coastal walkways.

This grade's value stems from its budget-friendly entry to TMCP benefits, ideal for SMEs where S355ML might over-spec at 25–35% higher cost. S275ML's high elongation (≥24%) suits cold forming (radius 2t), perfect for prefab in housing surges. Amid volatile markets, Gangsteel's mill links stabilize supply, with digital MTCs for full provenance.

Chemical Composition (Ladle Analysis, % max unless noted)

S275ML's makeup stresses cleanliness and balance, limiting P/S for toughness, with light alloying for weld synergy. Al-killed for sparse oxides.

*CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15; typical 0.27–0.33 for easy multi-run with E43xx. Nb/V pin grains to ASTM 10–12 for -50°C hold. For standard temp, see en 10025 4 s275m steel plate. Ca-Si optional for shape control, boosting feed rates.

Mechanical Properties (Transverse Testing)

S275ML's TMCP crafts a bendable matrix with pearlite aids, locking ReH and KV <4% scatter. Transverse confirmed; longitudinal 4–8% superior.

Hardness: 115–155 HBW. DBTT < -50°C. Fatigue: 140 MPa (10^7 cycles, R=0). UT EN 10160 S1/E1; MT optional. S275M moves KV to -20°C ≥40J.

Comparison of Materials Within the Standard

In EN 10025-4's TMCP spectrum, S275ML anchors the low-end with chill tolerance at entry pricing. This table juxtaposes it with peers—S275M (mild twin), S355M/ML (step-up), S420M/ML (elite)—focusing on power, cold hold, weld ease, and fit.

S275ML trails S275M by 20 USD/ton sans chill, suiting frosty vaults over sheds, but trails S355ML's 30% yield for 15% thinner in trusses—at 40% cost bump. Vs. S420ML, it prioritizes stretch (higher A%) and weld (lower CEV) for light fab vs. heavies. S275ML grabs 35% of EN 10025-4's base share (Eurofer stats), Gangsteel's SME favorite.

Applications & Design Considerations for S275ML

S275ML's chill poise and yield simplify Eurocode 3 shear proofs, trimming 10% vs. S235J2 in braces while padding impacts. Key fields:

• Cold Logistics: Fridge enclosures, ice rink bases—KV at -50°C bars snaps.
• Marine Lite: Dock fenders, wave barriers; fatigue EN 1993-1-9 > S235 (Δσ=150 MPa).
• Agri Cold: Frozen silos, chiller frames—low CEV seals lap welds.
• Temp Mods: Seasonal bridges, expo halls; Z25 stops cracks in clips.

Tips: Use E31xx 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.
