EN 10028-3 P355NH Steel Plate | P355NH Fine Grain Vessel Plate supplier

P355NH is the elevated-temperature quality in the P355 family of EN 10028-3. Buyers search EN 10028-3 P355NH, P355NH steel plate, 1.0565, P355NH fine grain vessel plate and P355NH supplier. The letters NH mean normalized fine-grain plate with specified elevated-temperature properties. This page is not P355N. N is room-temperature quality. This page is not P355NL1 or P355NL2. Those grades carry −40 °C or −50 °C impact. This page is not EN 10028-2 P355GH. GH is a different part of EN 10028. This page is not S355N. S355N is EN 10025-3 structural steel.

Yield is 355 MPa at ≤16 mm. Tensile is 490–630 MPa. Steel number is 1.0565. Delivery is normalized (+N). Elevated-temperature proof strength is the reason the H is in the name. Ask for that table when the vessel calculation uses design temperature. 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 10028-3, and ship it to fabricators in the USA, Europe, Middle East, Southeast Asia, Africa and South America.

If a drawing says P355N, we will not ship P355NH and call H extra without the buyer writing it. If a drawing says P355NL1, we will not ship P355NH and call 355 MPa enough. Dual marking is possible only when chemistry, tensile, impact, elevated-temperature values and delivery all fit both books.

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 vessel comparisons belong on GB/T 713.

Cast analysis follows EN 10028-3. Product analysis follows EN 10028-1 when ordered. Thickness can tighten carbon. Always read the certificate against the ordered thickness.

Cast Analysis and Product Analysis — EN 10028-3 P355NH (1.0565)

Aluminum minimum is there to kill the steel and help grain size. This is C-Mn fine-grain plate, not 0.3Mo and not 1.25Cr-0.5Mo. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Buyers search P355NH mechanical properties, P355NH yield strength and P355NH elevated temperature. Yield falls as thickness rises.

Tensile and Yield — EN 10028-3 P355NH

Elongation is typically 22% min on thinner plate. Impact for NH is commonly specified at 0 °C, 27 J, when the order names it. That is not −40 °C. Elevated-temperature proof strength is the NH item. Ask for the EN 10028-3 high-temperature table when the vessel calculation uses design temperature. SHH STEEL will not print those values on a P355N certificate and call it NH.

Do not treat 490–630 MPa tensile as permission to stamp Q345R steel plate or SA516 Grade 70 without checking both books.

P355NH is used on PED drums, shells and heat-exchanger courses that need 355 MPa fine-grain plate and elevated-temperature proof strength. That is the H. A designer who only wants room-temperature quality is asking for P355N. A designer who wants −40 °C Charpy is asking for P355NL1.

It is not a substitute for EN 10028-2 16Mo3. That grade is 0.3Mo. It is not a substitute for EN 10028-2 13CrMo4-5. That grade is 1.25Cr-0.5Mo. An ASME file should name SA-516 or SA-515 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.

P355NH is killed fine-grain C-Mn vessel plate in the 490–630 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 P355NH tensile band. A procedure written for SA516 Grade 60 may be light. A Cr-Mo procedure written for SA387 Grade 12 Class 1 is the wrong family. 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 P355NH (+N).

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 P355NH; 1.0565; 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 P355NH 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.

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. When dual-named against SA516 Grade 70, write whether EN 10029 or SA-20 governs thickness extra.

Charpy details. NH commonly uses 0 °C. Do not assume −40 °C.

Elevated-temperature proof strength. This is the NH item. Write the design temperatures needed on the certificate.

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

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.

P355NH is the plate for a file that wants 355 MPa fine-grain normalized steel and elevated-temperature values. It is the wrong plate for a winter tank at −40 °C. That work is P355NL1. It is the wrong plate for a file that only wants room-temperature quality. That work is P355N.

Experience on this grade is simple: keep the letters after P355. N, NH, NL1 and NL2 are four different purchase orders. SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) prices P355NH from first-line mills, reports 1.0565 chemistry as cast analysis and as product analysis when ordered, records +N, prints elevated-temperature values when ordered, and issues 3.1 as standard or 3.2 when specified.

We keep the grade on the order. P355NH is not P355N. P355NH is not P355NL1. P355NH is not EN 10028-2 P355GH. P355NH is not Q345R steel plate. If the drawing says P355N, we will not ship NH and call H free.

Company scope: global exporter SHH STEEL.
