EN 10028-4 11MnNi5-3 Steel Plate | 11MnNi5-3 0.5Ni Low Temp Vessel Plate
What is EN 10028-4 11MnNi5-3 Steel?
11MnNi5-3 is the lowest nickel step in EN 10028-4. Buyers search EN 10028-4 11MnNi5-3, 11MnNi5-3 steel plate, 1.6212, 11MnNi5-3 0.5Ni low temp vessel plate and 11MnNi5-3 supplier. Nickel is about 0.30–0.80%. That is why the title says 0.5Ni. This is not 12Ni14. 12Ni14 is 3.5Ni. This is not X8Ni9. X8Ni9 is 9Ni. This is not P355NL1. P355NL1 is EN 10028-3 carbon-manganese fine-grain plate without a specified nickel band of this type.
Yield is in the 355 MPa class at the usual thin-plate column. Tensile is 490–640 MPa. Steel number is 1.6212. Delivery is usually normalized (+N). Charpy is specified at −60 °C when the order follows this grade. 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 10028-4, and ship it to fabricators in the USA, Europe, Middle East, Southeast Asia, Africa and South America.
Do not ship 09MnNiDR steel plate against an 11MnNi5-3 drawing and call 0.5Ni automatic dual name unless both books are met. Do not ship SA203 Grade A and call nickel close. SA-203 Grade A is 2.25Ni. Dual marking is possible only when chemistry, tensile, impact temperature and delivery all fit.
Company scope: global exporter SHH STEEL.

This plate sits in pressure vessel steel plates. Chinese 0.5Ni / −70 °C comparisons belong on GB/T 713.3. 3.5Ni / 9Ni comparisons belong on GB/T 713.4 and ASME SA-203. Fine-grain carbon sisters belong on EN 10028-3, not on this nickel book.
Chemical Composition
Cast analysis follows EN 10028-4. Product analysis follows EN 10028-1 when ordered. People who search 11MnNi5-3 chemical composition and 1.6212 chemistry want nickel on the certificate, not a P355NL1 table copied across.

Nickel at 0.30–0.80% is the grade marker. That is 0.5Ni class, not 3.5Ni and not 9Ni. Carbon stays low because toughness at −60 °C is the job. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.
Mechanical Properties
Buyers search 11MnNi5-3 mechanical properties, 11MnNi5-3 yield strength and 11MnNi5-3 impact. Yield falls as thickness rises.
Tensile and Yield — EN 10028-4 11MnNi5-3
| Thickness (mm) | Yield min (MPa) | Tensile (MPa) |
|---|---|---|
| ≤ 16 | 355 | 490 – 640 |
| 16 – 40 | 345 | 490 – 640 |
| 40 – 60 | 335 | 490 – 640 |
| 60 – 100 | 315 | 470 – 640 |
| Density | 7.85 g/cm³ | 7.85 g/cm³ |
Elongation is typically 22% min on thinner plate. Charpy for this grade is −60 °C. Energy is commonly 27 J average when the order follows the book. Location and orientation must be written. Do not assume −70 °C. That is a different Chinese name. Do not assume −100 °C. That is 3.5Ni.
Do not quote 355 MPa yield on an 80 mm plate. Do not treat −60 °C as permission to stamp 09MnNiDR steel plate or SA203 Grade A without checking both books.

0.5Ni Low-Temperature Pressure-Vessel Service
Buyers pick 11MnNi5-3 when a PED file wants a little nickel for −60 °C toughness and does not want to jump to 3.5Ni or 9Ni. Search phrases such as 11MnNi5-3 boiler plate, 1.6212 steel plate and 11MnNi5-3 0.5Ni vessel plate all point here.
It is not a substitute for 08Ni3DR steel plate. That grade is 3.5Ni around −100 °C. It is not a substitute for 06Ni9DR steel plate. That grade is 9Ni −196 °C. It is not LNG inner-tank plate.
An ASME file that wants nickel vessel plate should name SA-203 on ASME SA203 and then write the grade. 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
11MnNi5-3 is 0.5Ni-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 −60 °C. A carbon procedure written for SA516 Grade 70 is not automatically valid. A 3.5Ni procedure written for SA203 Grade D is the next family, not this one. 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 10028-4 11MnNi5-3 (+N).
If the vessel will see PWHT, say so. Impact after simulated PWHT is worth naming on a −60 °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 10028-4 11MnNi5-3; 1.6212; heat number; cast analysis including nickel; product analysis when ordered; tensile to the correct thickness column; +N; Charpy at −60 °C when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.
Dimensions
Usual supply range from SHH STEEL for 11MnNi5-3 0.5Ni low temp vessel plate:
- Thickness: commonly 6 mm – 120 mm, thicker by mill agreement
- Width: 1500 mm – 4000 mm
- Length: 3000 mm – 12000 mm
3.5Ni plate belongs on 08Ni3DR steel plate. 9Ni plate belongs on 06Ni9DR steel plate.
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 −60 °C nickel plate without writing them.
Supplementary Requirements
Charpy details. Write −60 °C, joules, location and orientation.
Impact after simulated PWHT. When the vessel will be stress-relieved.
Product analysis. Especially nickel, P, S and Al.
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 10028-4 11MnNi5-3 shells at −60 °C |
| 0.5Ni storage / process drums | 11MnNi5-3 courses |
| Dual-certified export | 11MnNi5-3 / 09MnNiDR steel plate when both books fit |
| Comparison vs 3.5Ni | 11MnNi5-3 next to SA203 Grade D |
11MnNi5-3 is the plate for a PED file that wants a little nickel at −60 °C and does not want to pay 3.5Ni or 9Ni. It is the wrong plate for LNG inner tanks. That work belongs on 06Ni9DR steel plate.

Why Choose SHH STEEL
Experience on this grade is simple: 0.5Ni and −60 °C must both be on the certificate. SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) prices 11MnNi5-3 from first-line mills, reports 1.6212 chemistry including nickel, records +N, prints Charpy at −60 °C when ordered, and issues 3.1 as standard or 3.2 when specified.
We keep the grade on the order. 11MnNi5-3 is not 12Ni14. 11MnNi5-3 is not X8Ni9. 11MnNi5-3 is not P355NL1. 11MnNi5-3 is not Q345R steel plate. If the drawing says 3.5Ni, we will not ship 0.5Ni and call nickel close.
Company scope: global exporter SHH STEEL.
