Strength at operating temperature

For the ≤16 mm band, the minimum 0.2% proof stress decreases from 241 MPa at 100°C to 150 MPa at 400°C. Use the temperature that matches your design specification.

Pressure-equipment design approval

Table 4 values are material proof-stress requirements, not vessel allowable stresses. Determine design stress, corrosion allowance, operating life and code acceptance through the equipment designer.

Design boundary: EN 10028-2 Table 4 gives P265GH elevated-temperature strength values up to 400°C. This is not a blanket 400°C service rating, and it does not establish suitability for creep-controlled or higher-temperature design.
P265GH CAST ANALYSIS

P265GH Chemical Composition — EN 10028-2

The material number 1.0425 has its own manganese, carbon, residual and deoxidation requirements; each supplied heat should be checked.

Laboratory inspection of boiler steel test samples and chemical composition records

Specify chemistry and weldability together.

Request the actual heat chemistry and carbon equivalent when required by the project. EN 10028-2 permits an agreed maximum carbon equivalent for P265GH; it must be set at the enquiry stage.

Residual-element control: EN 10028-2 also limits Cr + Cu + Mo + Ni to 0.70% in cast analysis for this steel group. Product-analysis tolerances follow the separate standard table; do not substitute a product-analysis limit for a cast-analysis limit.
TRANSVERSE CHARPY V-NOTCH

Charpy Toughness and Test Scope

The standard lists several test temperatures; the purchase order and design code must identify which testing and reports are needed.

EN TABLE VALUE

+20°C / 40 J

The transverse Charpy V-notch value at +20°C is 40 J in EN 10028-2 Table 3. Use the specified test route and specimen rules.

OTHER TABLE TEMPERATURES

0°C / 34 J

EN 10028-2 also provides a transverse 34 J figure at 0°C. Confirm whether testing at this temperature is required for your equipment.

LOWER TEST TEMPERATURE

−20°C / 27 J

The table provides a transverse value of 27 J at −20°C. State the specified acceptance temperature, direction and witness requirements in the order.

Need a specific low-temperature impact record?

Send your design temperature, Charpy specimen orientation, minimum energy, test temperature and required certificate type.

+N / ORDER-AGREED CONDITIONS

P265GH Delivery Condition and Heat Treatment

Identify the supplied plate condition separately from any downstream forming, stress relief or fabrication heat treatment.

USUAL DELIVERY ROUTE

Normalized (+N)

Specify normalized steel plate when required by the drawing and review the declared condition on the mill certificate.

STANDARD-PERMITTED ROUTE

Normalizing Rolling

For P265GH, normalizing rolling can replace normalizing under EN 10028-2. Additional simulated-normalizing testing may be agreed in the purchase order.

SUBJECT TO AGREEMENT

Untreated Delivery

Untreated supply is possible only by agreement; test pieces must then demonstrate the properties in the usual prescribed delivery condition.

Normalizing guidance: EN 10028-2 Annex A lists a normalizing-temperature guideline of 890–950°C for P265GH. The actual thermal cycle is controlled by the approved steelworks and recorded as applicable.
Define the delivery condition before quoting.

Include +N, normalizing-rolled or specifically agreed untreated condition, and any post-forming or PWHT simulation.

Company-wide figures describe BAOSTEEL METAL operations, not the guaranteed output, inventory or mill approval of a specific P265GH grade or lot.

MILL & STOCK CONFIRMATION

Production Source, Plate Size and Availability

Specific P265GH availability is checked per mill and order; company inventory totals are not a stock commitment for this grade.

Confirm the producing mill and supply route.

BAOSTEEL METAL reviews P265GH requirements against the actual producing mill’s capabilities and available plate lots. We confirm production schedule, rolling range, surface condition, delivery condition and document support before issuing a firm offer.

  • Match steel grade, steel number and plate thickness band to the order.
  • Confirm actual stock, production lead time and accepted cutting size.
  • Review heat treatment, inspection unit and available EN 10204 route.
  • Coordinate marking, order quantity and shipment timing.

TESTING / HEAT TRACEABILITY

MTC, Charpy and Ultrasonic Inspection

Review the proposed mill’s documentary scope before purchase and retain plate-to-heat traceability after processing.

Keep test data connected to the finished plate.

Material certificates should identify the steel grade, heat number, inspection category, plate size and mechanical test results. Add supplementary tests according to the vessel design and buyer approval process.

  • EN 10204 3.1 or 3.2 inspection certificate as contracted.
  • Cast chemistry, heat identity, plate dimensions and normalized delivery state.
  • Transverse tensile results; Charpy results at the order-defined temperature.
  • UT scope and acceptance class, optional HIC, high-temperature tensile or third-party witnessing where ordered.

3.2 certificate scope: Request the actual independent inspection and witnessing process at order placement. An EN 10204 3.1 certificate does not automatically meet a contractual 3.2 requirement.
FABRICATION / CODE ACCEPTANCE

Welding, Forming and PWHT Review

Share the fabrication and design-temperature requirements so the proposed plate and its inspection package are suitable for the intended boiler component.

WELDING

WPS/PQR and weldability

BUYER QUESTIONS

P265GH Boiler Steel Plate FAQ

Use the exact plate thickness, equipment code and material-document requirements when comparing quotations.

What is P265GH boiler steel plate?

P265GH (1.0425) is a non-alloy EN 10028-2 pressure-purpose steel grade with specified elevated-temperature properties, used in code-approved boilers and welded pressure equipment.

What is the minimum P265GH yield strength?

EN 10028-2 specifies 265 MPa for thicknesses up to 16 mm. The required minimum decreases with thickness, reaching 185 MPa above 150 mm up to 250 mm.

How does 200°C strength compare with room temperature?

For plate up to 16 mm, EN 10028-2 Table 4 gives minimum Rp0.2 of 205 MPa at 200°C. At room temperature the minimum yield ReH is 265 MPa for that thickness band.

What is the usual delivery condition?

The usual condition is normalized (+N). Normalizing rolling may replace normalizing under the standard; untreated supply requires agreement and prescribed test conditions.

What are the P265GH Charpy values?

The EN table lists transverse values of 40 J at +20°C, 34 J at 0°C and 27 J at −20°C. Confirm the contracted impact test temperature, specimen size and acceptance route.

Is EN 10204 3.1 the same as 3.2?

No. The certificates involve different inspection and endorsement arrangements. Specify the required document and independent witness scope during the enquiry.

Does P265GH contain 0.25–0.35% molybdenum?

No. That is characteristic of 16Mo3. EN 10028-2 lists a maximum 0.08% Mo cast-analysis limit for P265GH.

Can P265GH be substituted for P355GH or ASTM A516?

Only after review and approval under the relevant vessel design code and buyer specification. These grades do not share identical chemical and mechanical requirements.

Can you supply ultrasonic-tested or cut plates?

UT and basic plate cutting may be arranged where supported by the actual producing mill and order. State the test method, acceptance class, cut list and marking requirements.

What details are needed for a bulk quote?

Send P265GH / 1.0425, standard edition, thickness, width, length, total quantity, +N or agreed delivery, test scope, certificate type, Incoterm and destination.
