EN 10028-3 P275NH Steel Plate | P275NH Fine Grain Vessel Plate supplier

P275NH is the 275 MPa normalized fine-grain grade in EN 10028-3. Buyers search EN 10028-3 P275NH, P275NH steel plate, 1.0486, P275NH fine grain vessel plate and P275NH supplier. NH means the plate carries specified elevated-temperature properties on a normalized fine-grain route. This page is not EN 10028-2 P265GH. P265GH is non-alloy high-temperature plate without the EN 10028-3 fine-grain quality system. This page is not P275NL1 and not P275NL2. Those sisters are low-temperature qualities.

Yield is 275 MPa at ≤16 mm. Tensile is 390–510 MPa. Steel number is 1.0486. Delivery is normalized (+N). Grain refining (Al, and Nb/Ti/V when used) is part of the book. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) supplying this grade to the USA, Europe, Middle East, Southeast Asia, Africa and South America.

Do not ship EN 10028-2 P265GH against a P275NH drawing and call 265 close to 275. Do not ship EN 10028-2 P355GH and call carbon the same as fine-grain NH. Do not ship Q245R steel plate unless both books are written. Dual marking is possible only when chemistry, tensile, impact, grain and delivery all fit.

Company scope: global exporter SHH STEEL.

This plate sits in pressure vessel steel plates and carbon steel plates. EN 10028-2 high-temperature sisters belong on EN 10028-2. Chinese low-temperature sisters belong on GB/T 713.3. Fine-grain structural steel is a different book: EN 10025-3.

Cast analysis follows EN 10028-3. Product analysis follows EN 10028-1 when ordered. People who search P275NH chemical composition and 1.0486 chemistry want a fine-grain killed analysis, not a P355GH table copied across.

Cast Analysis and Product Analysis — EN 10028-3 P275NH (1.0486)

Aluminum minimum is there to kill the steel and help grain size. Niobium, titanium and vanadium stay limited. This is still a C-Mn fine-grain plate, not 0.3Mo and not 1.25Cr-0.5Mo. SHH STEEL reports cast analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Buyers search P275NH mechanical properties, P275NH yield strength and P275NH tensile strength. Yield falls as thickness rises. Use the thickness column on the mill certificate.

Tensile and Yield — EN 10028-3 P275NH

Elongation is typically 24% min on thinner plate. Impact for NH quality is commonly specified at 0 °C, 27 J, when the order names it. Elevated-temperature proof strength is the NH reason for existing. Ask for that table when the vessel calculation uses design temperature.

Do not quote 275 MPa yield on an 80 mm plate. Do not treat 390–510 MPa tensile as permission to stamp SA516 Grade 60 or Q245R steel plate without checking both books.

Search habits mix P275NH equivalent, 1.0486 equivalent and P275NH vs P265GH. Those names help a buyer find the right page. They do not authorize substitution.

Buyers pick P275NH when a PED file wants normalized fine-grain plate at the 275 MPa step with elevated-temperature values, and does not need P355NH strength or NL1 / NL2 impact. Search phrases such as P275NH boiler plate, P275NH pressure vessel plate and 1.0486 steel plate all point here.

It is not a substitute for 16MnDR steel plate. That grade is GB/T 713.3 −40 °C plate. It is not a substitute for 09MnNiDR steel plate. That grade is −70 °C nickel plate. It is not 0.3Mo plate like EN 10028-2 16Mo3.

An ASME file should name SA-516 or SA-662 and then write extras. 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.

P275NH is killed fine-grain C-Mn vessel plate in the 390–510 MPa tensile band. 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 the P275NH tensile band. A procedure written for SA516 Grade 70 is stronger metal and is not automatically valid. A Cr-Mo procedure written for SA387 Grade 12 Class 1 is the wrong family. Fine-grain plate usually welds cleanly if heat input and hydrogen are controlled. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Usual delivery from SHH STEEL is normalized EN 10028-3 P275NH (+N). As-rolled is not the default for this book. Buyers who search P275NH normalized or P275NH +N are asking for this route.

If the vessel will see PWHT, say so. Test coupons then follow a simulated cycle. 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 P275NH; 1.0486; heat number; cast analysis; product analysis when ordered; tensile to the correct thickness column; +N; impact when ordered; elevated-temperature values when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.

Usual supply range from SHH STEEL for P275NH fine grain vessel plate:

• Thickness: commonly 6 mm – 150 mm, thicker by mill agreement
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm

Ship plate inquiries belong on shipbuilding steel plates. Structural fine-grain plate belongs on EN 10025-3, not on this vessel page.

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 fine-grain vessel plate without writing them.

Charpy details. Temperature, energy, location and orientation. NH is not NL1. Do not assume −40 °C.

Product analysis. Add this when the destination file wants finished-plate chemistry.

Elevated-temperature proof strength. This is the NH item. Write it when the calculation uses design temperature.

Simulated PWHT. When the equipment will be stress-relieved.

NDE. EN 10160 or the named UT class.

Third-party. EN 10204 3.2 when written.

SHH STEEL sources EN 10028-3 P275NH from first-line Chinese mills and ships it on worldwide terms.

SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). On EN 10028-3 P275NH that means mill pricing from Wuyang, Angang, Baosteel and other first-line mills, 1.0486 chemistry reported as cast analysis and as product analysis when ordered, recorded +N, tensile to the correct thickness column, 3.1 as standard and 3.2 when specified.

We keep the grade on the order. P275NH is not P275NL1. P275NH is not EN 10028-2 P265GH. P275NH is not Q345R steel plate. If the drawing says P355NH, we will not ship P275NH and call fine grain close.

Company scope: global exporter SHH STEEL.
