Whether you're sourcing for European offshore wind farms, American bridge retrofits, or Asian shipyards, Gangsteel bridges standards like EN 10025-4 with ASTM, JIS, GB/T, and more—ensuring seamless certification and cost savings. Z25/Z35 through-thickness available ex-stock, 100% UT EN 10160 S2/E2 standard. Fast delivery worldwide (3–7 days to major ports). Discover our full en 10025 4 High Strength Structural Steel lineup for related options.
S355ML equivalent material refers to international steel grades that match or closely approximate the properties of S355ML under EN 10025-4:2004 (2019 revision)—a thermomechanically rolled (TMCP) weldable fine-grain structural steel with 355 MPa minimum yield strength and ≥27 J Charpy V-notch impact at –50 °C longitudinally.The "S355ML" designation breaks down as: "S" for structural, "355" for yield (MPa, ≤16 mm), "M" for TMCP delivery, and "L" for low-temperature toughness.
TMCP—hot rolling at 900-1100 °C with controlled cooling (20-40 °C/s)—creates a refined ferrite-bainite microstructure, ensuring CEV ≤0.39 for preheat-free welding up to 80 mm and fine grains (ASTM 8-10) for ductility (≥22% elongation). Equivalents are crucial for multinational projects, allowing substitution without re-qualification under codes like Eurocode 3 or DNV-OS-B101. Common scenarios include replacing S355ML with ASTM A572 Gr.50 + Z35 for U.S. bridges or Q355E for Chinese-EU hybrids.
Gangsteel supplies S355ML and equivalents with dual certification, ideal for seamless transitions. For grade basics, see S355ML Meaning EN 10025-4 Structural Steel Supplier. Our equivalents reduce lead times by leveraging local stock while maintaining EN 10025-4 compliance.
S355ML's chemistry is tightly controlled for weldability and toughness; equivalents share similar limits.

Q1: Best S355ML equiv for U.S. projects?
A: A572 Gr.50 + Z35; yield 345 MPa close, but add –50 °C KV testing for full match. A633 Gr.C alt for normalized. Dual-cert for AISC 360; Gangsteel supplies with U.S. stamps.
Q2: JIS SM490A vs S355ML?
A: SM490A Rm 490 MPa equiv, –40 °C KV standard; S355ML TMCP finer HAZ. For Japanese-Polish JV, SM490A cost-effective; Gangsteel offers both with JIS certs.
Q3: Q355E (GB) substitution?
A: Exact low-temp match per GB/T 1591; CEV similar. Ideal China-EU; Gangsteel dual EN/GB MTCs for Belt & Road.
Q4: API 2W Gr.50 for offshore?
A: Yes, weldable equiv; S355ML LT superior (CTOD opt). For Gulf/Baltic, API RP 2Z; stock with DNV approval.
Q5: S355QL (EN 10025-6) alt?
A: QT version same strength; S355ML cheaper, no distortion. For lifts, QL if >500 MPa needed; both stocked.
Q6: Equiv price diff?
A: Equivs 10-30 USD/t cheaper (local stock); S355ML premium for TMCP. FOB 680-780 USD/t equiv (25 mm).
Q7: Lead time for equivs?
A: Stock 2-4 days; processed 3-6 days; mill 4 weeks. Dual-cert +1 week.
