Hindustan Steel Corporation offers EN 10028-2 P265GH and P355NH plates, designed specifically for welded pressure vessels, heat exchangers, and high-temperature boilers operating under elevated pressure. These plates conform to European standards for non-alloy and alloy steels intended for pressure equipment service.
Sourced from reputed mills in Europe, Korea, and India, our P265GH and P355NH plates offer excellent formability, weldability, and long-term strength under cyclic thermal stress. We stock them with EN 10204 3.1 / 3.2 certification, UT-tested, and ready for export to the Gulf, Africa, and Southeast Asia.
P265GH and P355NH are grades under EN 10028-2, a European specification for pressure vessel steels used in steam, oil & gas, and thermal applications.
Both materials are heat-treated for consistent mechanical properties, especially in high-pressure hydrogen, hot liquid, or cyclic steam environments.
These plates are used in a wide range of critical pressure environments, such as:
We also supply IBR-approved and PED-certified plates for international fabrication projects.
| Property | P265GH | P355NH |
|---|---|---|
| Minimum Yield Strength | 265 MPa | 355 MPa |
| Tensile Strength | 410–530 MPa | 490–630 MPa |
| Elongation (%) | ≥ 25% | ≥ 22% |
| Impact Energy (Charpy V @ -20°C) | Not guaranteed | Min 27J (normalized condition) |
| Max Service Temperature | ~450°C | ~500°C (cyclic safe) |
P355NH offers higher strength, better notch toughness, and is ideal for normalized high-pressure environments.
EN 10028-2 P265GH and P355NH are part of the European standard for pressure vessel steels. These grades comply with essential welding, forming, and heat resistance norms and are widely accepted in global fabrication codes.
| Standard | P265GH Equivalent | P355NH Equivalent |
|---|---|---|
| ASME/ASTM | ASTM A516 Gr 60 (approx.) | ASTM A516 Gr 70N (approx.) |
| DIN | DIN 17155 HII | StE 355 / WStE 355 |
| BS | BS 1501 161 430A | BS 1501 224 490B |
| IS (India) | IS 2041 Gr 265 | IS 2041 Gr 355 |
We also supply dual-certified plates meeting PED, CE, and IBR regulations — with full test documentation for international use.
Hindustan Steel Corporation stocks EN 10028 P265GH and P355NH plates in mill-standard and cut-to-size formats:
Available Range:
We also offer CNC plasma cutting, edge preparation, and stamping for fabrication-ready delivery.
Both P265GH and P355NH plates are delivered in the normalized (N) or normalized rolled (N/QT) condition, ensuring optimal grain structure and mechanical uniformity.
This makes them highly suitable for code-stamped vessels and refinery-grade fabrication.
EN 10028 steel plates are engineer-friendly and suitable for welding, forming, and machining.
Plates can be supplied with bevelled edges, UT test reports, and stamping per project spec.
We help EPCs, boiler manufacturers, and chemical plant contractors reduce downtime with weldable, code-compliant, fabrication-friendly steel.
If you’re comparing alternatives or designing for diverse conditions, consider:
We also stock HIND Boiler Plates, our proprietary line of certified pressure vessel steels.
Hindustan Steel Corporation is a leading exporter of EN 10028 P265GH and P355NH plates to global boiler and pressure vessel manufacturers, EPC firms, and fabrication yards.

Packing Standards:
We ensure safe and certified global delivery, aligned with project timelines.
| Design Consideration | Suggested Grade |
|---|---|
| Standard pressure applications | P265GH |
| Higher pressure, normalized steel | P355NH |
| Better notch toughness | P355NH (tested at -20°C) |
| Medium to high temperature | P355NH (~500°C+) |
| Cost-effective boiler plates | P265GH |
Pro Tip:
If your project involves hydrogen service, temperature cycling, or PED compliance, choose P355NH. For general boilers and piping, P265GH offers great value.
All our EN 10028-2 plates are backed with full traceability and compliance, including:
We ensure that your steel plates meet all international boiler code requirements.
P355NH has higher strength, better impact resistance, and is always supplied normalized.
Yes, especially due to its fine-grain structure and impact-tested condition.
Normalized heat treatment – essential for elevated temperature performance.
Roughly equivalent in composition and usage, though not identical.
Yes, we supply P355NH plates with IBR Form III for Indian boiler codes.
Typically up to 500°C for continuous service, depending on design.
Carbon ~0.2%, Manganese ~1.0–1.5%, with Silicon, Sulphur, and Phosphorus.
Yes, both grades offer excellent weldability with conventional techniques.
Yes, due to higher yield and impact performance.
Absolutely, especially when used in pressure-rated vessels.
490–630 MPa, depending on thickness and normalization.
Yes, we provide full edge prep and heat stamping per order.
Stock plates: 2–3 days. Custom sizes: 7–10 working days.
Yes, on request. We supply CE and EN 10204 3.2 certified plates for PED.
