EN 10028-3 P355NL2 Steel Plate | P355NL2 -50°C Vessel Plate supplier
What is EN 10028-3 P355NL2 Steel ?
P355NL2 is the −50 °C quality in the P355 family of EN 10028-3. Buyers search EN 10028-3 P355NL2, P355NL2 steel plate, 1.1106, P355NL2 -50°C vessel plate and P355NL2 supplier. NL2 is colder than NL1. This page is not P355NL1. NL1 is −40 °C. This page is not P355N. N is room-temperature quality. This page is not P355NH. NH is elevated-temperature quality. 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 1.1106. Delivery is normalized (+N). Charpy is specified at −50 °C when the order follows NL2. 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 P355NL1, we will not ship P355NL2 and call colder automatically better without the buyer writing the name. If a drawing says −50 °C, we will not ship NL1 and call minus forty close. Dual marking with 15MnNiNbDR steel plate is possible only when both books are fully met.
Company scope: global exporter SHH STEEL.

Nickel may sit toward the top of the residual band because NL2 is a colder toughness quality. Sulfur and phosphorus stay tight. This is still C-Mn fine-grain plate, not 3.5Ni and not 9Ni. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.
Mechanical Properties
Buyers search P355NL2 mechanical properties, P355NL2 impact and P355NL2 -50°C. Yield still falls with thickness. Impact is the NL2 item.
Tensile and Yield — EN 10028-3 P355NL2
| 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 NL2 is −50 °C. Energy is commonly 27 J average when the order follows the book. Location and orientation must be written. Do not assume NL1 −40 °C is enough for an NL2 drawing.
Do not quote 355 MPa yield on an 80 mm plate. Do not treat −50 °C as permission to stamp 15MnNiNbDR steel plate or SA662 Grade C without checking both books.

-50°C Fine-Grain Pressure-Vessel Service
Buyers pick P355NL2 when a PED file wants 355 MPa fine-grain plate and Charpy at −50 °C. Search phrases such as P355NL2 -50°C, P355NL2 boiler plate and 1.1106 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 around −100 °C. It is not LNG inner-tank plate. That work belongs on 06Ni9DR steel plate.
An ASME file should name SA-662 with the matching impact extra, or SA-516 with a written −50 °C test. 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
P355NL2 is killed fine-grain C-Mn vessel plate at a colder impact temperature than NL1. 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 −50 °C, not only at −40 °C. A procedure written for SA516 Grade 70 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 P355NL2 (+N).
If the vessel will see PWHT, say so. Impact after simulated PWHT should be named on a −50 °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 P355NL2; 1.1106; heat number; cast analysis; product analysis when ordered; tensile to the correct thickness column; +N; Charpy at −50 °C when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.
Dimensions
Usual supply range from SHH STEEL for P355NL2 -50°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 −50 °C plate without writing them. When dual-named against SA662 Grade C, write whether EN 10029 or SA-20 governs thickness extra.
Supplementary Requirements
Charpy details. Write −50 °C, joules, location and orientation. Do not write “impact as per EN 10028-3” and expect the mill to guess 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 P355NL2 shells at −50 °C |
| Cold storage / tank farms | P355NL2 courses |
| Heat-exchanger shells | P355NL2 channels from SHH STEEL |
| Dual-certified export | P355NL2 / 15MnNiNbDR steel plate when both books fit |
| ASME comparison jobs | P355NL2 next to SA662 Grade C |
P355NL2 shows up on European equipment that is colder than NL1 and 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 a file that only wants elevated-temperature proof strength. That work is P355NH. It is the wrong plate for −40 °C only. That work is P355NL1.
Supply Capability

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 P355NL2 from first-line mills, reports 1.1106 chemistry, records +N, prints Charpy at −50 °C when ordered, and issues 3.1 as standard or 3.2 when specified.
We keep the grade on the order. P355NL2 is not P355NL1. P355NL2 is not P355NH. P355NL2 is not P355N. P355NL2 is not Q345R steel plate. If the drawing says −40 °C, we will not ship NL2 and call colder automatically better without the buyer writing the name.
Company scope: global exporter SHH STEEL.
