EN 10028-4 X12Ni5 Steel Plate | X12Ni5 5Ni Low Temp Vessel Plate supplier

X12Ni5 is the 5Ni grade in EN 10028-4. Buyers search EN 10028-4 X12Ni5, X12Ni5 steel plate, 1.5680, X12Ni5 5Ni low temp vessel plate and X12Ni5 supplier. Nickel is about 4.75–5.25%. That is why the title says 5Ni. This is not 12Ni14. 12Ni14 is 3.5Ni. This is not X8Ni9. X8Ni9 is 9Ni. This is not 13MnNi6-3. That grade is 0.75Ni.

Yield is in the 390 MPa class at the usual thin-plate column. Tensile is 530–710 MPa. Steel number is 1.5680. Delivery is usually normalized and tempered (+NT). Charpy is specified at −120 °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 07Ni5DR steel plate against an X12Ni5 drawing and call 5Ni automatic dual name unless both books are met. Do not ship SA203 Grade E and call 3.5Ni close to 5Ni. 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 5Ni belongs on GB/T 713.4. 3.5Ni ASME comparisons belong on ASME SA-203. 9Ni Chinese comparisons belong on 06Ni9DR steel plate.

Cast analysis follows EN 10028-4. Product analysis follows EN 10028-1 when ordered. People who search X12Ni5 chemical composition and 1.5680 chemistry want 5% nickel on the certificate, not a 12Ni14 table copied across.

Cast Analysis and Product Analysis — EN 10028-4 X12Ni5 (1.5680)

Nickel at 4.75–5.25% is the grade marker. That is 5Ni, not 3.5Ni and not 9Ni. Carbon stays low because toughness at −120 °C is the job. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Buyers search X12Ni5 mechanical properties, X12Ni5 yield strength and X12Ni5 impact. Yield falls as thickness rises.

Tensile and Yield — EN 10028-4 X12Ni5

Elongation is typically 20% min on thinner plate. Charpy for this grade is −120 °C. Energy is commonly 27 J or 40 J average when the order follows the book. Location and orientation must be written. Do not assume −100 °C from 12Ni14 is enough. Do not assume −196 °C. That is 9Ni.

Do not quote 390 MPa yield on an 80 mm plate. Do not treat −120 °C as permission to stamp 07Ni5DR steel plate or SA203 Grade E without checking both books.

Buyers pick X12Ni5 when a PED file wants 5Ni plate at about −120 °C and does not want to jump to 9Ni. Search phrases such as X12Ni5 5Ni, 1.5680 steel plate and X12Ni5 low temp vessel plate all point here.

It is not a substitute for 08Ni3DR steel plate. That grade is 3.5Ni. 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 the correct SA-203 or 9Ni book, not assume 5Ni equals 3.5Ni. 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.

X12Ni5 is 5Ni 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 match 5Ni practice and keep toughness at −120 °C. A 3.5Ni procedure written for SA203 Grade D is the previous family. A 9Ni procedure written for X8Ni9 is the next family. A carbon procedure written for SA516 Grade 70 is not automatically valid. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Usual delivery from SHH STEEL is normalized and tempered EN 10028-4 X12Ni5 (+NT).

If the vessel will see PWHT, say so. Impact after simulated PWHT is worth naming on a −120 °C 5Ni 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 X12Ni5; 1.5680; heat number; cast analysis including nickel; product analysis when ordered; tensile to the correct thickness column; +NT; Charpy at −120 °C when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.

Usual supply range from SHH STEEL for X12Ni5 5Ni low temp vessel plate:

• Thickness: commonly 6 mm – 100 mm, thicker by mill agreement
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm

3.5Ni plate is 12Ni14 / 08Ni3DR steel plate. 9Ni plate belongs on 06Ni9DR steel plate.

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 −120 °C 5Ni plate without writing them.

Charpy details. Write −120 °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.

X12Ni5 is the plate for a PED file that wants 5Ni at about −120 °C and is not yet 9Ni. It is the wrong plate for LNG inner tanks. That work belongs on 06Ni9DR steel plate.

Experience on this grade is simple: 5Ni and −120 °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 X12Ni5 from first-line mills, reports 1.5680 chemistry including nickel, records +NT, prints Charpy at −120 °C when ordered, and issues 3.1 as standard or 3.2 when specified.

We keep the grade on the order. X12Ni5 is not 12Ni14. X12Ni5 is not X8Ni9. X12Ni5 is not Q345R steel plate. If the drawing says 9Ni, we will not ship 5Ni and call nickel close.

Company scope: global exporter SHH STEEL.
