What is S355MC Equivalent EN 10025-4 Structural Steel?

S355MC is a hot-rolled, high-strength, low-alloy (HSLA) steel for cold forming specified in EN 10149-2, with:

  • Minimum yield strength 355 MPa
  • Excellent formability (guaranteed bending values)
  • No mandatory low-temperature impact toughness (optional –20 °C)

While S355MC is designed for cold forming (truck chassis, crane booms, roll-formed sections), many projects require structural grades with guaranteed impact toughness and better weldability.

The closest EN 10025-4 structural equivalents to S355MC are:

Grade (EN 10025-4)

Key Match to S355MC

Difference & Advantage

S355M

Same yield 355 MPa, same CEV

+ Guaranteed –20 °C impact, better weld HAZ

S355ML

Same yield 355 MPa, same CEV

+ Guaranteed –50 °C impact, offshore preferred

S420M/ML

Higher yield 420 MPa

For higher strength needs

S460M/ML

Higher yield 460 MPa

For maximum strength-to-weight

S355M and S355ML are the direct structural replacements for S355MC when the application requires welding instead of cold forming, or when low-temperature toughness is specified.

Gangsteel supplies dual-certified plates that meet both EN 10149-2 S355MC and EN 10025-4 S355M/ML when properties overlap.

FAQ – Quick Answers

Q1: Can I use S355MC instead of S355M 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 S355M instead of S355MC?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 S355M, 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 S355M plates and S355MC coils/plates ready.

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