What is EN 10028-2 P265GH Steel Plate?
P265GH is a non-alloy elevated-temperature steel plate specified under European
standard EN 10028-2, engineered specifically for pressure vessels and high-temperature equipment. It is widely specified across petrochemical processing, power generation, and boiler manufacturing industries. In its grade designation, "P" stands for pressure equipment service, "265" represents the minimum room-temperature yield strength of 265 MPa, and "GH" denotes its performance stability in elevated-temperature environments ("G" for high temperature, "H" for heat-resistant). As an internationally recognized pressure vessel steel grade, P265GH is a premier material choice for medium- to high-pressure vessel fabrication due to its excellent mechanical properties and versatile fabricability.

EN 10028-2 P265GH Hot Rolled Carbon Plate Delivery Conditions & Heat Treatment
Standard Delivery Condition: Normalized (+N), involving heating and soaking at 880–940°C (1616–1724°F) followed by air cooling. This produces a uniform ferrite-pearlite fine-grained microstructure with low residual internal stress. Normalizing rolling (+NR) can also be supplied per contract agreement.
Post-Weld Stress Relieving (PWHT): Soaking at 600–650°C (1112–1202°F), furnace cooling down to 300°C (572°F), followed by air cooling. Quenching and tempering (Q+T) strengthening processes are not applicable to this grade.
EN 10028-2 P265GH Non Alloy Plate Fabrication & Weldability
Weldability: A core technical advantage-exhibits superior weldability. Preheating is generally unnecessary for plate thicknesses $\le 25\text{ mm}$. For gauges > 25mm, a moderate preheat of 100–150°C (212–302°F) using low-hydrogen consumables ensures an extremely low risk of cold cracking.
Hot & Cold Forming: Demonstrates good cold-bending performance with a minimum bend radius of approximately 3 times plate thickness. The hot working temperature window is 900–1050°C (1652–1922°F), with a final forging/rolling temperature not lower than 800°C (1472°F). Conventional thermal cutting methods-including oxy-fuel, plasma, and laser-are fully applicable.
P265GH Hot Rolled Steel Plate Core Application
- Boiler Manufacturing (Primary End-Use): Industrial steam boiler
drums, waterwall headers, hot water boiler shell rings, and heat recovery steam generator (HRSG) casings. - Pressure Vessel Fabrication: Oil & gas surge drums, steam receivers/blowdown tanks, shell-and-tube heat exchanger shells and tubesheets, non-corrosive/neutral service reactor shells, and air compressor receiver tanks.
- Chemical & Energy Equipment: Low-temperature medium-pressure heat exchangers, water treatment pressure vessels, and balance-of-plant (BOP) low-pressure pressure-retaining components for power generation.
- PED-Compliant Export Equipment: Pressure vessel plate fully compliant with the European Pressure Equipment Directive (PED 2014/68/EU), serving as a dedicated grade for boiler and pressure vessel export projects destined for European and Western markets.
- Piping Systems & Structural Components: Submerged arc welded (SAW) large-diameter elevated-temperature pressure piping, pressure vessel blind/weld-neck flanges, and forged tubesheet blanks.
Key Cost Factors for P265GH Plate
Thickness Range: Heavy-gauge plates typically command higher unit prices due to increased rolling difficulty and reduced mill yield rates. Ultra-thin gauges (< 8mm) may also incur processing premiums.
Dimensional Specifications: Non-standard widths or cut-to-length sizes requiring custom rolling campaigns will impact pricing and manufacturing lead times.
Order Volume: Scale economies apply-larger procurement tonnages generally qualify for more competitive per-ton pricing.
Supplementary Testing Requisites: Mandatory non-destructive testing (NDT) such as Ultrasonic Testing (UT), Hydrogen-Induced Cracking (HIC) testing, Through-Thickness Z-direction testing (Z15/Z25/Z35), and NACE compliance certification add testing costs as required by project specifications.
Market Dynamics: Mill base prices fluctuate with raw material inputs (iron ore, scrap, alloys), energy surcharges, and global supply-demand balances. Mill quotations are typically valid for 7 to 14 days.
Incoterms & Delivery Terms: Pricing varies based on chosen Incoterms (FOB, CFR, CIF, or DDP), reflecting freight modes, insurance coverage, and destination port logistics.

FAQ
What is the price per kg of P265GH plate?
The price of P265GH steel plate generally ranges from $0.50 to $1.00 per kg (or about $513 to $1,000 per ton), depending on order volume, thickness, and market conditions.
Why is P265GH called the "best balance point" in the EN 10028-2 grade family?
P265GH offers the optimal combination of strength (265 MPa), weldability (CEV ≤ 0.43), formability, and cost. It provides sufficient strength for most pressure vessel applications while maintaining straightforward fabrication - making it the default choice when no special high-strength or high-temperature requirement dictates a different grade.
What is the ASTM equivalent of P265GH?
The nearest ASTM equivalent is A516 Gr.60. However, they are not identical - they differ in chemical composition limits, impact energy requirements, and testing conventions. Substitution requires engineering review and should be based on EN 10028-2 certification.
