EN 10028-4 15NiMn6 Steel Plate | 15NiMn6 Ni-Mn Low Temp Vessel Plate
What is EN 10028-4 15NiMn6 Steel?
15NiMn6 is the higher Ni-Mn step in the low-nickel end of EN 10028-4. Buyers search EN 10028-4 15NiMn6, 15NiMn6 steel plate, 1.6228, 15NiMn6 Ni-Mn low temp vessel plate and 15NiMn6 supplier. Nickel is about 1.20–1.70%. Manganese is about 0.80–1.50%. This is not 11MnNi5-3. That grade is 0.5Ni. This is not 13MnNi6-3. That grade is 0.75Ni. This is not 12Ni14. 12Ni14 is 3.5Ni. This is not X8Ni9. X8Ni9 is 9Ni.
Yield is in the 390 MPa class at the usual thin-plate column. Tensile is 530–710 MPa. Steel number is 1.6228. Delivery is usually normalized (+N). Charpy is specified at −80 °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 13MnNi6-3 against a 15NiMn6 drawing and call 0.75Ni close to 1.5Ni. Do not ship 15MnNiNbDR steel plate and call the names identical unless both books are met. Do not ship SA203 Grade A. That grade is 2.25Ni. Dual marking is possible only when chemistry, tensile, impact temperature and delivery all fit.

Chemical Composition
Cast analysis follows EN 10028-4. Product analysis follows EN 10028-1 when ordered. People who search 15NiMn6 chemical composition and 1.6228 chemistry want nickel and manganese on the certificate, not a 13MnNi6-3 table copied across.
Cast Analysis and Product Analysis — EN 10028-4 15NiMn6 (1.6228)
| Element | Cast Analysis (%) | Product Analysis, when ordered (%) |

Nickel at 1.20–1.70% is the grade marker. That is still a Ni-Mn plate, not 3.5Ni and not 9Ni. Carbon stays limited because toughness at −80 °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 15NiMn6 mechanical properties, 15NiMn6 yield strength and 15NiMn6 impact. Yield falls as thickness rises.
Tensile and Yield — EN 10028-4 15NiMn6
| Thickness (mm) | Yield min (MPa) | Tensile (MPa) |
|---|---|---|
| ≤ 16 | 390 | 530 – 710 |
| 16 – 40 | 380 | 530 – 710 |
| 40 – 60 | 370 | 520 – 700 |
| 60 – 100 | 350 | 510 – 690 |
| Density | 7.85 g/cm³ | 7.85 g/cm³ |
Elongation is typically 20% min on thinner plate. Charpy for this grade is −80 °C. Energy is commonly 27 J average when the order follows the book. Location and orientation must be written. Do not assume −60 °C from 11MnNi5-3 is enough. Do not assume −100 °C. That is 3.5Ni.
Do not quote 390 MPa yield on an 80 mm plate. Do not treat −80 °C as permission to stamp 15MnNiNbDR steel plate or SA203 Grade A without checking both books.

Ni-Mn Low-Temperature Pressure-Vessel Service
Buyers pick 15NiMn6 when a PED file wants more nickel than 13MnNi6-3 and a 390 MPa step, without jumping to 3.5Ni. Search phrases such as 15NiMn6 boiler plate, 1.6228 steel plate and 15NiMn6 Ni-Mn 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
15NiMn6 is Ni-Mn vessel plate at about 1.5% nickel. 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 −80 °C. A carbon procedure written for SA516 Grade 70 is not automatically valid. A 0.75Ni procedure written for 13MnNi6-3 is the previous family. A 3.5Ni procedure written for SA203 Grade D is the next 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 10028-4 15NiMn6 (+N).
If the vessel will see PWHT, say so. Impact after simulated PWHT is worth naming on a −80 °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 15NiMn6; 1.6228; heat number; cast analysis including nickel and manganese; product analysis when ordered; tensile to the correct thickness column; +N; Charpy at −80 °C when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.
Dimensions
Usual supply range from SHH STEEL for 15NiMn6 Ni-Mn low temp vessel plate:
- Thickness: commonly 6 mm – 120 mm, thicker by mill agreement
- Width: 1500 mm – 4000 mm
- Length: 3000 mm – 12000 mm
0.5Ni plate is 11MnNi5-3. 0.75Ni plate is 13MnNi6-3. 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 −80 °C Ni-Mn plate without writing them.
Supplementary Requirements
Charpy details. Write −80 °C, joules, location and orientation.
Impact after simulated PWHT. When the vessel will be stress-relieved.
Product analysis. Especially nickel, manganese, 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 15NiMn6 shells at −80 °C |
| Ni-Mn storage / process drums | 15NiMn6 courses |
| Dual-certified export | 15NiMn6 / 15MnNiNbDR steel plate when both books fit |
| Comparison vs 3.5Ni | 15NiMn6 next to SA203 Grade D |
15NiMn6 is the plate for a PED file that wants more nickel than 13MnNi6-3 and a 390 MPa step, without paying 3.5Ni or 9Ni. It is the wrong plate for LNG inner tanks. That work belongs on 06Ni9DR steel plate.
Supply Capability
SHH STEEL sources EN 10028-4 15NiMn6 from first-line Chinese mills and ships it on worldwide terms.

Why Choose SHH STEEL
Experience on this grade is simple: Ni-Mn chemistry and −80 °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 15NiMn6 from first-line mills, reports 1.6228 chemistry including nickel, records +N, prints Charpy at −80 °C when ordered, and issues 3.1 as standard or 3.2 when specified.
We keep the grade on the order. 15NiMn6 is not 13MnNi6-3. 15NiMn6 is not 12Ni14. 15NiMn6 is not X8Ni9. 15NiMn6 is not Q345R steel plate. If the drawing says 3.5Ni, we will not ship 1.5Ni and call nickel close.
Company scope: global exporter SHH STEEL.
