EN 10028-2 P355GH Steel Plate | P355GH High Temp Vessel Plate

P355GH is the higher-strength carbon grade in EN 10028-2. Buyers search EN 10028-2 P355GH, P355GH high temp vessel plate, 1.0473 and P355GH steel plate. GH means elevated-temperature properties. This page is not EN 10028-3 fine-grain low-temperature plate and not EN 10028-4 nickel plate.

Yield is 355 MPa at ≤16 mm. Tensile is 510–650 MPa. Steel number is 1.0473. Delivery is usually normalized (+N). SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) for this grade.

Do not ship P265GH against a P355GH drawing. P265GH yield is 265 MPa. The closest Chinese carbon vessel name is often Q345R steel plate. The closest ASME carbon comparison is often SA516 Grade 70 carbon steel plates or ASTM A516 Grade 70. Dual marking is possible only when chemistry, tensile, impact and delivery all fit. Do not ship Q245R steel plate or SA516 Grade 60 carbon steel plates and call 60 the same as P355GH.

Company scope: global steel mill sourcing partner – SHH STEEL.

This plate sits in pressure vessel steel plates and carbon steel plates. ASME carbon comparisons belong on ASME SA516 and ASTM A516.

Cast analysis follows EN 10028-2 Table 1. Product analysis follows EN 10028-1 when ordered.

Cast Analysis and Product Analysis — EN 10028-2 P355GH (1.0473)

P355GH carries more manganese than P265GH. That is why yield sits at 355 MPa. It is still killed carbon steel, not Cr-Mo and not 9Ni. SHH STEEL reports cast analysis on every certificate and product analysis when the order names it. Density is 7.85 g/cm³.

Room-temperature values below are the usual thickness columns. Yield falls as thickness rises. Use the thickness column on the mill certificate.

Tensile and Yield — EN 10028-2 P355GH

Elongation is typically 20% min on thinner plate. Impact at 0 °C, 27 J, is the usual option when the order names it. Elevated-temperature proof strength is part of EN 10028-2. Ask for Table 5 values when the vessel calculation uses design temperature.

Do not quote 355 MPa yield on a 80 mm plate. Do not treat 510–650 MPa tensile as permission to stamp Q370R steel plate without checking both books.

Comparison names help a buyer search. They do not authorize substitution.

Buyers pick P355GH for PED boilers, steam drums, heat-exchanger shells and high-temperature carbon vessels that need more strength than P265GH. It is the European carbon grade most often compared with Q345R steel plate and SA516 Grade 70 carbon steel plates.

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 06Ni9DR steel plate. That grade is 9Ni −196 °C plate. It is not Cr-Mo plate like 15CrMoR steel plate.

An ASME file should name the SA/ASTM grade on ASME SA516 or ASME SA515 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.

P355GH is killed carbon vessel plate at the 510–650 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. ASME dual-name work uses ASME Section IX. Consumables must match the P355GH tensile band, not a P265GH procedure copied without review. A Q345R steel plate procedure is a comparison only. A Cr-Mo procedure written for 14Cr1MoR steel plate is the wrong family. Preheat follows thickness and hydrogen control. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Usual delivery from SHH STEEL is normalized EN 10028-2 P355GH (+N). As-rolled is not the default for pressure work.

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 10028-2 P355GH; 1.0473; 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 P355GH high temp 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 plate belongs on structural steel plates or EN 10025-2. Stainless inquiries belong on stainless steel products.

Dimensional limits follow EN 10028-1 and EN 10029 unless the order names another tolerance table. Do not apply ASTM A36/A36M structural tolerances to a PED vessel plate without writing them.

Charpy details. Temperature, energy, location and orientation. 0 °C / 27 J is common, not assumed.

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

Elevated-temperature proof strength. Add this 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 is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). On EN 10028-2 P355GH that means mill pricing, 1.0473 chemistry reported as cast analysis and as product analysis when ordered, recorded +N, tensile results to the correct thickness column, 3.1 as standard and 3.2 when specified.

We keep the grade on the order. P355GH is not P265GH. P355GH is not Q245R steel plate. P355GH is not SA516 Grade 60 carbon steel plates. If the drawing says P265GH, we will not ship P355GH and call carbon close unless the buyer writes both names.
