S460M vs S460ML – The Complete Impact Toughness Comparison

S460M and S460ML are identical twin grades in EN 10025-4 with the same chemistry, same strength, same weldability, and same TMCP delivery condition.

The only difference is the Charpy V-notch impact test temperature:

Property	S460M	S460ML	Winner for Impact-Critical Projects
Standard	EN 10025-4	EN 10025-4	—
Impact Test Temperature	–20 °C	–50 °C	S460ML
Minimum KV (longitudinal)	≥40 J	≥27 J	S460ML(tougher at lower temp)
Typical Actual KV (Gangsteel)	80–200 J at –20 °C	100–250 J at –50 °C	S460ML
Yield Strength ReH (MPa)	460 → 350–380 (by thickness)	Identical	Tie
Tensile Strength Rm (MPa)	540–720	Identical	Tie
Elongation A5 (%)	≥17	Identical	Tie
CEV max	0.48	Identical	Tie
Preheat-free Welding (mm)	Up to 80	Up to 80	Tie
Price (November 2025)	Baseline	+80–150 USD/ton	S460M cheaper, S460ML better value in cold
Market Share (Offshore Wind)	15–25 %	75–85 %	S460MLdominates

Bottom line: If your lowest service temperature is above –20 °C → S460M is sufficient and slightly cheaper. If your lowest service temperature is below –20 °C (most offshore wind, Arctic, cold-region bridges) → S460ML is mandatory and has become the default choice in 90 % of new projects.

The price difference is easily justified by the much higher safety margin against brittle fracture in low temperatures.

 

Chemical Composition – Identical for Both Grades

S460M and S460ML have exactly the same chemical requirements.

Ladle Analysis (max % unless noted)

Element	C	Si	Mn	P	S	Nb	V	Al min	Ti	Cr	Ni	Mo	Cu	N	CEV max
S460M / S460ML	0.16	0.60	1.70	0.025	0.020	0.05	0.12	0.020	0.05	0.30	0.80	0.20	0.55	0.025	0.48

Typical Gangsteel actual values: C 0.10–0.14 %, CEV 0.42–0.46.

Mechanical Properties – Identical Except Impact Temperature

Thickness (mm)	ReH min (MPa)	Rm (MPa)	A5 min (%)	KV min (J) at test temperature
≤16	460	540–720	17	S460M: 40 J @ –20 °C S460ML: 27 J @ –50 °C
16<t≤40	440	540–720	17	same
40<t≤63	430	540–720	17	same
63<t≤80	410	540–720	17	same
80<t≤100	400	540–720	17	same
100<t≤150	370–385	530–710	17	same
150<t≤200	350–380*	530–710	17	same

Gangsteel actual higher values. Hardness 160–210 HBW. Full tables: S355ML Mechanical Properties EN 10025-4 Plate Supplier (same as S460ML).

 

Weldability – Both Excellent (Identical)

Both grades have the same low CEV, so welding behaviour is identical:

• No preheating required up to 80 mm thickness
• Low-hydrogen consumables recommended
• Maximum heat input 3.5–4.5 kJ/mm to preserve HAZ toughness

 

Price Difference and Market Reality

Grade	Price Level (November 2025)	When to Choose
S460M	Baseline	Service temperature ≥ –20 °C
S460ML	+80–150 USD/ton	Service temperature < –20 °C (offshore wind, Arctic, cold bridges)

The extra cost of S460ML is easily justified by the much higher safety margin against brittle fracture in low temperatures.

FAQ – Detailed Answers

Q1: S460M vs S460ML – which is better for offshore wind?

A: S460ML is now the standard choice for offshore wind (used in 90 % of new projects) because it guarantees impact toughness at –50 °C instead of –20 °C. Most offshore wind specifications (DNV-OS-B101, Norsok M-120) require –40 °C or –50 °C design temperature for safety margin.

Q2: Are the mechanical properties identical except impact temperature?

A: Yes – yield strength, tensile strength, elongation, hardness, density, and weldability are exactly the same. Only the Charpy impact test temperature and minimum energy differ.

Q3: Price difference today?

A: S460ML is approximately 80–150 USD/ton higher than S460M (November 2025 market), but the extra toughness is worth it for any project below –20 °C service temperature.

Q4: Can I use S460M instead of S460ML to save money?

A: Only if your specification allows it and the lowest service temperature is above –20 °C. Most modern offshore and cold-region projects require S460ML.

Q5: Do you have both grades in stock right now?

A: Yes – very large stock of both S460M and S460ML in all common thicknesses, ready for immediate delivery.

Q6: Z35 availability for both grades?

A: Yes – large stock of S460M + Z35 and S460ML + Z35 ready.

Q7: Delivery time to Europe or USA?

A: From ready stock: 7–12 days to Rotterdam, Antwerp, Houston, or Los Angeles.
