S355ML vs S355MC EN 10025-4 Coil Plate Supplier

S355ML vs S355MC EN 10025-4 Coil Plate Supplier

Gangsteel – China's Leading Mill-Direct Supplier & Exporter of S355ML vs S355MC EN 10025-4 Coil and Plate Structural Steel

Gangsteel is the professional supplier you can trust for both S355ML plates (EN 10025-4) and S355MC coil/plates (EN 10149-2), with the largest combined stock in Asia – over 8,000 tons ready for immediate delivery in thickness 6–200 mm (plates) or 1.5–20 mm (coils), width 1500–4200 mm, length/coil weight up to 18 m/30 tons. All material is genuine TMCP produced by top mills (HBIS, Shougang) with full European approvals and third-party inspection (DNV, ABS, LR, BV, CCS, KR, TÜV, SGS).

We supply both grades with Z35 through-thickness quality in stock for plates, 100 % UT EN 10160 S2/E2 standard, and full documentation.

S355ML vs S355MC – Different Standards, Different Applications

S355ML and S355MC have the same nominal yield strength of 355 MPa, but they are completely different materials from different standards with different purposes:

Bottom line: These two grades are not interchangeable.

• Choose S355ML when you need welded structural components with low-temperature toughness (offshore wind, Arctic, bridges).
• Choose S355MC when you need high formability for cold bending/roll forming (truck frames, crane arms, trailers).

Many customers confuse the two because both are TMCP 355 MPa steels, but they serve completely different markets.

Gangsteel supplies both grades with full certification and can help you choose the correct one for your application.

Chemical Composition – Very Similar but Different Limits

The main difference is in microalloying levels – S355MC has higher Nb+V+Ti limits to achieve better formability in cold bending.

Mechanical Properties – Same Strength, Different Focus

S355ML is designed for welded structures with low-temp toughness. S355MC is designed for cold forming with guaranteed bending performance.

Weldability – S355ML Is Better for Welding

S355ML has lower CEV and is specifically designed for welding (including high heat input SAW). S355MC is optimized for cold forming, not heavy welding – HAZ softening can occur with high heat input.

Applications – Completely Different Markets

FAQ – Quick Answers

Q1: Can I use S355MC instead of S355ML to save money?A: No – they are for different applications. S355MC has no low-temperature guarantee and is not designed for heavy welding.

Q2: Can I use S355ML for cold forming?A: Yes, but S355MC is better and cheaper for cold forming applications.

Q3: Which is better for offshore wind?A: S355ML – low-temp toughness and Z35 are mandatory.

Q4: Price difference?A: S355MC is 80–150 USD/ton cheaper than S355ML, but not interchangeable.

Q5: Do you supply S355MC in plates or only coils?A: We supply S355MC in both coils and cut-to-length plates.

Q6: Do you have both grades in stock?A: Yes – very large stock of both S355ML plates and S355MC coils/plates ready.

Q7: Delivery time?A: Stock material 3–7 days worldwide.
