What is EN 10028-3 P355NL1 Steel?
P355NL1 is the −40 °C quality in the P355 family of EN 10028-3. Buyers search EN 10028-3 P355NL1, P355NL1 steel plate, 1.0566, P355NL1 -40°C vessel plate and P355NL1 supplier. NL1 is the low-temperature letter set. This page is not P355N. N is room-temperature quality. This page is not P355NH. NH is elevated-temperature quality. This page is not P355NL2. NL2 is −50 °C. This page is not EN 10028-2 P355GH. This page is not S355NL. S355NL is EN 10025-3 structural steel.
Yield is 355 MPa at ≤16 mm. Tensile is 490–630 MPa. Steel number is 1.0566. Delivery is normalized (+N). Charpy is specified at −40 °C when the order follows NL1. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). We buy this grade from qualified Chinese mills, check the certificate against EN 10028-3, and ship it to fabricators in the USA, Europe, Middle East, Southeast Asia, Africa and South America.
If a drawing says P355N, we will not ship P355NL1 and call 355 enough. If a drawing says P355NL2, we will not ship P355NL1 and call minus forty close to minus fifty. Dual marking with 16MnDR steel plate is possible only when both books are fully met.

Chemical Composition
Cast analysis follows EN 10028-3. Product analysis follows EN 10028-1 when ordered.
Cast Analysis and Product Analysis — EN 10028-3 P355NL1 (1.0566)

|---|---|---|
| Carbon (C), max | 0.18 | 0.20 |

Nickel may sit toward the top of the residual band because NL1 is a toughness quality. Sulfur and phosphorus stay tight. This is still C-Mn fine-grain plate, not 3.5Ni. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.
Mechanical Properties
Buyers search P355NL1 mechanical properties, P355NL1 impact and P355NL1 -40°C. Yield still falls with thickness. Impact is the NL1 item.
Tensile and Yield — EN 10028-3 P355NL1
| Thickness (mm) | Yield min (MPa) | Tensile (MPa) |
|---|---|---|
| ≤ 16 | 355 | 490 – 630 |
| 16 – 40 | 345 | 490 – 630 |
| 40 – 60 | 335 | 490 – 630 |
| 60 – 100 | 315 | 470 – 630 |
| 100 – 150 | 295 | 460 – 630 |
| Density | 7.85 g/cm³ | 7.85 g/cm³ |
Elongation is typically 22% min on thinner plate. Charpy for NL1 is −40 °C. Energy is commonly 27 J average when the order follows the book. Location and orientation must be written. Do not assume NL2 −50 °C on this page.
Do not quote 355 MPa yield on an 80 mm plate. Do not treat −40 °C as permission to stamp 16MnDR steel plate or SA516 Grade 70 without checking both books.

-40°C Fine-Grain Pressure-Vessel Service
Buyers pick P355NL1 when a PED file wants 355 MPa fine-grain plate and Charpy at −40 °C. Search phrases such as P355NL1 -40°C, P355NL1 boiler plate and 1.0566 steel plate all point here.
It is not a substitute for 09MnNiDR steel plate. That grade is −70 °C. It is not a substitute for 08Ni3DR steel plate. That grade is 3.5Ni. An ASME file should name SA-662 or SA-516 with a written −40 °C extra. Dual marking is possible only when both books are met.
SHH STEEL supplies this plate to fabricators in the United States, Mexico, South America, Europe, the Middle East, Africa and Asia.
Weldability
P355NL1 is killed fine-grain C-Mn vessel plate. Treat welding as production welding, and as PED / ASME Code welding when the equipment is a vessel.
Qualify to the applicable code. Consumables must keep toughness at −40 °C. A procedure written for SA516 Grade 70 without an impact extra is not automatically valid. A nickel procedure written for SA203 Grade D is the wrong family. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.
Heat Treatment and Delivery Condition
Usual delivery from SHH STEEL is normalized EN 10028-3 P355NL1 (+N).
If the vessel will see PWHT, say so. Impact after simulated PWHT is worth naming on a −40 °C file. Extra simulation, 3.2 hold points or special NDE add time. Plan about two months when those extras are on the order.
The certificate lists EN 10028-3 P355NL1; 1.0566; heat number; cast analysis; product analysis when ordered; tensile to the correct thickness column; +N; Charpy at −40 °C when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.
Dimensions
Usual supply range from SHH STEEL for P355NL1 -40°C vessel plate:
- Thickness: commonly 6 mm – 150 mm, thicker by mill agreement
- Width: 1500 mm – 4000 mm
- Length: 3000 mm – 12000 mm
Structural fine-grain plate belongs on EN 10025-3. Ship plate belongs on shipbuilding steel plates.
Tolerances
Dimensional limits follow EN 10028-1 and EN 10029 unless the order names another table. Class A is the usual default. If the calculation used minimum thickness after corrosion, write the allowed minus. Do not apply ASTM A36 structural tolerances to a PED −40 °C plate without writing them. When dual-named against SA516 Grade 70, write whether EN 10029 or SA-20 governs thickness extra.
Supplementary Requirements
Charpy details. Write −40 °C, joules, location and orientation. Do not write “impact as per EN 10028-3” and expect NL2.
Impact after simulated PWHT. When the vessel will be stress-relieved.
Product analysis. Especially P, S, Al and N.
Through-thickness / Z-test. When the plate is a thick nozzle or pad.
NDE. EN 10160 or ASTM A435 / A578 as named.
Third-party. EN 10204 3.2 when written.
Applications
| Industry | Typical components |
|---|---|
| PED low-temp vessels | EN 10028-3 P355NL1 shells at −40 °C |
| Storage tanks and drums | P355NL1 courses |
| Heat-exchanger shells | P355NL1 channels from SHH STEEL |
| Dual-certified export | P355NL1 / 16MnDR steel plate when both books fit |
| ASME comparison jobs | P355NL1 next to SA662 Grade B |
P355NL1 is the plate for a 355 MPa PED file at −40 °C that is not yet in the 3.5Ni book. It is the wrong plate for LNG inner tanks. That work belongs on 06Ni9DR steel plate. It is the wrong plate for −50 °C. That work is P355NL2.

Why Choose SHH STEEL
Experience on this grade is simple: keep the letters after P355. N, NH, NL1 and NL2 are four different purchase orders. SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) prices P355NL1 from first-line mills, reports 1.0566 chemistry, records +N, prints Charpy at −40 °C when ordered, and issues 3.1 as standard or 3.2 when specified.
We keep the grade on the order. P355NL1 is not P355N. P355NL1 is not P355NH. P355NL1 is not P355NL2. P355NL1 is not Q345R steel plate. If the drawing says −50 °C, we will not ship NL1 and call minus forty close.
