EN 10028-4 X10Ni9 Steel Plate | X10Ni9 9Ni -196°C Vessel Plate supplier

X10Ni9 is the third 9Ni name in EN 10028-4. Buyers search EN 10028-4 X10Ni9, X10Ni9 steel plate, 1.5665, X10Ni9 9Ni -196°C vessel plate, X10Ni9 LNG and X10Ni9 supplier. Nickel is about 8.50–9.50%. This page is not X8Ni9. X8Ni9 is steel number 1.5662. This page is not X7Ni9. X7Ni9 is steel number 1.5663. This page is not 12Ni14. 12Ni14 is 3.5Ni. This page is not X12Ni5. X12Ni5 is 5Ni.

Yield is in the 490 MPa class after quench and temper. Tensile is 640–840 MPa. Steel number is 1.5665. Delivery is usually quenched and tempered (QT). Charpy is specified at −196 °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 X8Ni9 or X7Ni9 against an X10Ni9 drawing and call 9Ni the same. Do not ship 06Ni9DR steel plate and call 9Ni automatic dual name unless both books are met. Dual marking is possible only when chemistry, tensile, impact temperature and delivery all fit.

This plate sits in pressure vessel steel plates and nuclear-grade steel plates when the project file uses that path. Chinese 9Ni belongs on GB/T 713.4. 3.5Ni ASME comparisons belong on ASME SA-203.

Cast analysis follows EN 10028-4. Product analysis follows EN 10028-1 when ordered. People who search X10Ni9 chemical composition and 1.5665 chemistry want 9% nickel on the certificate, not an X8Ni9 table copied across.

Cast Analysis and Product Analysis — EN 10028-4 X10Ni9 (1.5665)

Nickel at 8.50–9.50% is the grade marker. Carbon on X10Ni9 may sit a little higher than on X7Ni9. That is why the names are not interchangeable. This is still 9Ni, not 5Ni and not 3.5Ni. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Buyers search X10Ni9 mechanical properties, X10Ni9 yield strength and X10Ni9 -196°C. Strength comes from quench and temper.

Tensile and Yield — EN 10028-4 X10Ni9

Elongation is typically 18% min on thinner plate. Charpy for this grade is −196 °C. Energy is commonly 70 J average when the LNG file names that value, or 27 J when the order follows the base book. Location and orientation must be written. Do not assume an X8Ni9 or X7Ni9 certificate covers X10Ni9.

Do not quote 490 MPa yield on a plate that was only normalized. Do not treat −196 °C as permission to stamp 06Ni9DR steel plate without checking both books.

Buyers pick X10Ni9 when a PED / LNG file names this exact 9Ni designation. Search phrases such as X10Ni9 LNG, X10Ni9 -196°C and 1.5665 steel plate all point here.

It is not a substitute for 08Ni3DR steel plate. That grade is 3.5Ni. It is not a substitute for 07Ni5DR steel plate. That grade is 5Ni. It is not a substitute for Q400GMDR steel plate. That grade is high-Mn cryogenic plate, not 9Ni.

An ASME file should name A353 / SA-353 or A553 Type I / SA-553. 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.

X10Ni9 is 9Ni cryogenic vessel plate. Treat welding as production welding, and as PED / ASME Code welding when the equipment is an LNG tank or cryogenic vessel.

Qualify to the applicable code. Consumables must match 9Ni practice and keep toughness at −196 °C. A 3.5Ni procedure written for SA203 Grade D is the previous family. A 5Ni procedure written for X12Ni5 is the previous family. An X8Ni9 or X7Ni9 procedure is a sister procedure, not an automatic cover. A carbon procedure written for SA516 Grade 70 is not valid. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Usual delivery from SHH STEEL is quenched and tempered EN 10028-4 X10Ni9 (QT). Double-normalize routes exist on related ASME 9Ni books. Write the route on the order.

If the tank will see a heat cycle, say so. Many 9Ni tanks limit conventional carbon-steel PWHT. Impact after any simulated cycle must be named. 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 X10Ni9; 1.5665; heat number; cast analysis including nickel; product analysis when ordered; tensile to the correct thickness column; QT; Charpy at −196 °C when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.

Usual supply range from SHH STEEL for X10Ni9 9Ni -196°C vessel plate:

• Thickness: commonly 6 mm – 80 mm, thicker by mill agreement
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm

Sister 9Ni names are X8Ni9 and X7Ni9. 5Ni plate is X12Ni5 / 07Ni5DR steel plate. 3.5Ni plate is 12Ni14 / 08Ni3DR steel plate. Chinese 9Ni is 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 −196 °C 9Ni plate without writing them. When dual-named against 06Ni9DR or A553 Type I, write which thickness table governs.

Charpy details. Write −196 °C, joules, location and orientation. LNG files often want 70 J, not only 27 J.

Impact after simulated heat treatment. When the tank procedure uses a cycle.

Product analysis. Especially nickel, carbon, P, S and Al.

NDE. EN 10160 or ASTM A435 / A578 as named. LNG tanks often add tighter UT.

Third-party. EN 10204 3.2 when written.

X10Ni9 is the plate for a PED / LNG file that names this exact 9Ni designation. It is the wrong plate for a −40 °C carbon tank. That work is P355NL1. It is the wrong plate for 3.5Ni at −100 °C. That work is 12Ni14.
