S275M vs S275ML – The Complete Low-Temperature Comparison

S275M and S275ML 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	S275M	S275ML	Winner for Low-Temp Projects
Standard	EN 10025-4	EN 10025-4	—
Impact Test Temperature	–20 °C	–50 °C	S275ML
Minimum KV (longitudinal)	≥40 J	≥27 J	S275ML(much safer below –20 °C)
Typical Actual KV (Gangsteel)	80–200 J at –20 °C	100–250 J at –50 °C	S275ML
Yield Strength ReH (MPa)	275 → 215–225 (by thickness)	Identical	Tie
Tensile Strength Rm (MPa)	370–530	Identical	Tie
Elongation A5 (%)	≥24	Identical	Tie
CEV max	0.38	Identical	Tie
Preheat-free Welding (mm)	Up to 100	Up to 100	Tie
Price (December 2025)	Baseline	+50–80 USD/ton	S275M cheaper, S275ML better value in cold
Market Share (Cold-Region Projects)	30–40 %	60–70 %	S275MLdominates

Bottom line:

• Service temperature ≥ –20 °C → S275M is sufficient and saves money
• Service temperature < –20 °C (cold storage, northern bridges, light offshore) → S275ML is mandatory and has become the default choice in 70 % of new projects

The price difference is easily recovered by the dramatically higher safety margin against brittle fracture in cold environments.

 

Chemical Composition – Identical for Both Grades

S275M and S275ML 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
S275M / S275ML	0.14	0.50	1.50	0.030	0.025	0.05	0.10	0.020	0.05	0.30	0.30	0.10	0.55	0.015	0.38

Typical Gangsteel actual values: C 0.09–0.12 %, CEV 0.32–0.36.

 

Mechanical Properties – Identical Except Impact Temperature

Thickness (mm)	ReH min (MPa)	Rm (MPa)	A5 min (%)	KV min (J) at test temperature
≤16	275	370–530	24	S275M: 40 J @ –20 °C S275ML: 27 J @ –50 °C
16<t≤40	265	370–530	24	same
40<t≤63	255	370–530	24	same
63<t≤80	245	370–530	24	same
80<t≤100	235	370–530	24	same
100<t≤120	235	360–520	24	same
120<t≤150	225	360–520	24	same
150<t≤200	215–225*	360–520	24	same

*Gangsteel actual higher values. Hardness 130–170 HBW.

 

Weldability – Both Excellent (Identical)

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

• No preheating required up to 100 mm thickness
• Low-hydrogen consumables recommended
• Maximum heat input 3.0–4.0 kJ/mm to preserve HAZ toughness

Price Difference and Market Reality

Grade	Price Level (December 2025)	When to Choose
S275M	Baseline	Service ≥ –20 °C
S275ML	+50–80 USD/ton	Service < –20 °C (cold storage, northern infrastructure)

The extra cost of S275ML is easily justified by the higher safety margin in low temperatures.

FAQ – Detailed Answers

Q1: S275M vs S275ML – which is better for cold storage warehouses?

A: S275ML is the standard choice for cold storage (used in 80 % of new projects) because it guarantees impact toughness at –50 °C instead of –20 °C. Most cold storage specifications 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: S275ML is approximately 50–80 USD/ton higher than S275M (December 2025 market), but the extra toughness is worth it for any project below –20 °C service temperature.

Q4: Can I use S275M instead of S275ML to save money?

A: Only if your specification allows it and the lowest service temperature is above –20 °C. Most modern cold-region projects require S275ML.

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

A: Yes – very large stock of both S275M and S275ML in all common thicknesses, ready for immediate delivery.

Q6: Z35 availability for both grades?

A: Yes – large stock of S275M + Z35 and S275ML + Z35 ready.

Q7: Delivery time to Europe or USA?

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