Compare all 4 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
normalized then stress relieved / simulated PWHT | Used when plate must survive vessel PWHT (typ. 580–620 °C) — slightly softened, toughest and most dimensionally stable condition. | 270 | 425 | 32 | 124 HB | 11 % IACS |
NDefault Normalized | Standard delivery condition for EN 10028-2 plate, EN 10216-2/10217-2 tube and EN 10222-2 forgings — best combination of toughness and uniform fine grain. | 285 | 440 | 30 | 130 HB | — |
as-rolled / hot rolled (thin plate, strip and welded tube base material) | Cheapest condition for thin sections where the rolling schedule already gives fine grain; slightly higher strength, lower and more scattered toughness. | 300 | 455 | 27 | 138 HB | — |
Quenched and tempered | Optional condition for thick EN 10222-2 forgings needing higher through-thickness strength and low-temperature toughness. | 325 | 480 | 26 | 150 HB | 11 % IACS |
What is P245GH?
P245GH (1.0352, cross-referenced to 20R and A515 Gr.60) is a non-alloy carbon steel for boilers and pressure vessels, one strength step above P195GH, supplied normalized, as-rolled, normalized and stress-relieved, or quenched and tempered. It is used for plate and forgings in elevated-temperature service, offering 285 MPa yield, 440 MPa tensile, 30 % elongation, 130 HB and service to 400 °C. Weldability remains high (score 92) but formability is lower than P195GH, and the bare surface flash-rusts, so blasting and priming are mandatory. P245GH has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,460°C (2,660 °F). P245GH has a yield strength of 285 MPa (41.3 ksi) and a tensile strength of 440 MPa (63.8 ksi) — weaker than 89% of steel grades. Elongation at break is 30% and the elastic modulus is 212 GPa (30.7 Msi).

Working with P245GH
Is P245GH easy to machine?
Machines like ordinary low-carbon steel: gummy chips, use sharp positive-rake carbide, generous coolant and moderate speeds (~120–180 m/min carbide turning).
Can P245GH be welded?
Excellent weldability with SMAW/GMAW/SAW using E7018 or ER70S-6 class consumables; preheat usually unnecessary below ~30 mm, PWHT 580–620 °C per EN 13445/AD 2000 for thick sections.
Can P245GH be formed, bent or molded?
Cold rolls, dishes and flanges readily (min bend radius ≈1–1.5 t); hot forming 900–1050 °C followed by re-normalizing to restore grain size.

P245GH — frequently asked
What is P245GH used for?
P245GH is typically used for boiler components, pressure vessel flanges, steam drums and heat exchanger shells. In short: stronger than P195GH; code pressure vessel plate; weldable at 440 MPa.
What is the yield strength of P245GH?
P245GH has a typical yield strength of 285 MPa (41.3 ksi) and a tensile strength of 440 MPa (63.8 ksi) — weaker than 89% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is P245GH easy to machine?
Reasonably — machinability is rated good (62/100, better than 89% of steel grades). Machines like ordinary low-carbon steel: gummy chips, use sharp positive-rake carbide, generous coolant and moderate speeds (~120–180 m/min carbide turning).
Can P245GH be welded?
Yes — weldability is rated excellent (92/100). Excellent weldability with SMAW/GMAW/SAW using E7018 or ER70S-6 class consumables; preheat usually unnecessary below ~30 mm, PWHT 580–620 °C per EN 13445/AD 2000 for thick sections.
