EN 10028-3 P460NH Steel Plate | P460NH Fine Grain Vessel Plate supplier

P460NH is the elevated-temperature quality in the P460 family of EN 10028-3. Buyers search EN 10028-3 P460NH, P460NH steel plate, 1.8935, P460NH fine grain vessel plate and P460NH supplier. The letters NH mean normalized fine-grain plate with specified elevated-temperature properties. This page is not P460NL1. NL1 is −40 °C. This page is not P460NL2. NL2 is −50 °C. This page is not P355NH. That grade is a 355 MPa step. This page is not S460N. S460N is EN 10025-3 structural steel.

Yield is 460 MPa at ≤16 mm. Tensile is 570–720 MPa. Steel number is 1.8935. 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 P460NL1, we will not ship P460NH and call 460 enough. If a drawing says P355NH, we will not ship P460NH and call stronger automatically acceptable. Dual marking with Q460R steel plate is possible only when both books are fully met.

Company scope: global exporter SHH STEEL.

This plate sits in pressure vessel steel plates and carbon steel plates. Chinese vessel comparisons belong on GB/T 713. EN 10028-2 high-temperature sisters belong on EN 10028-2.

Cast analysis follows EN 10028-3. Product analysis follows EN 10028-1 when ordered.

Cast Analysis and Product Analysis — EN 10028-3 P460NH (1.8935)

460 MPa comes from fine grain plus normalizing, not from a high-carbon melt. This is still 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 P460NH mechanical properties, P460NH yield strength and P460NH elevated temperature. Yield falls as thickness rises.

Tensile and Yield — EN 10028-3 P460NH

Elongation is typically 17–19% 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 P460NL1 certificate and call it NH.

Do not quote 460 MPa yield on an 80 mm plate. Do not treat 570–720 MPa tensile as permission to stamp Q460R steel plate or SA537 Class 1 without checking both books.

P460NH is used on PED drums, shells and heat-exchanger courses that need 460 MPa fine-grain plate and elevated-temperature proof strength. That is the H. A designer who wants −40 °C Charpy is asking for P460NL1. A designer who only wants 355 MPa NH is asking for P355NH.

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-537 or SA-516 / 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.

P460NH is killed fine-grain C-Mn vessel plate at 570–720 MPa tensile. 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 460 MPa / 570–720 MPa band. A procedure written for SA516 Grade 70 may be light on strength. A Cr-Mo procedure written for SA387 Grade 12 Class 1 is the wrong family. Heat input and hydrogen control matter more at this strength than on P355NH. 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 P460NH (+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 P460NH; 1.8935; 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 P460NH fine grain vessel plate:

• Thickness: commonly 8 mm – 120 mm, thicker by mill agreement
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm

Structural 460 fine-grain plate belongs on EN 10025-3. QT high-strength plate belongs on EN 10025-6.

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 460 MPa plate without writing them. When dual-named against Q460R steel plate, write which thickness table governs.

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. Especially P, S, Al, N, Nb and V.

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.

P460NH is the plate for a 460 MPa PED file that needs elevated-temperature values and does not name NL impact. It is the wrong plate for a winter tank at −40 °C. That work is P460NL1. It is the wrong plate for −50 °C. That work is P460NL2.

Experience on this grade is simple: 460 MPa and the H must both be on the certificate. SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) prices P460NH from first-line mills, reports 1.8935 chemistry, 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. P460NH is not P460NL1. P460NH is not P460NL2. P460NH is not P355NH. P460NH is not Q345R steel plate. If the drawing says P355NH, we will not ship 460 and call stronger automatically acceptable.

Company scope: global exporter SHH STEEL.
